Why SUN and MOON both are considered as planet in Hindu astrology ? while modern science consider SUN as Star and Moon as natural satellite

Astrological knowledge is given to the world by Hinduism. From ancient time astrology is used to predict future of a person, area, nation and earth to be protected from natural calamities. On the position of planet in horoscope prepared from Birth time, Birth date and Birth place, future of some one is predicted. In astrology, nine planets are there, those are Sun (Surya), Moon (Chandra),  Mercury (Buddha), Venus (Sukra), Mars (Mangal), Jupiter (Brihaspati), Saturn (Sani), Rahu and Ketu.

When according to science there are only eight planets and one planets is removed from class of planet. Name of those eight planets according to science are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. While Plutos is removed from class of planets. According to modern science, definition of a planet in solar system is the heavenly body which revolve around the Sun which is considered as center of Solar system and the satellites (Sub planets) are those heavenly bodies which are revolved around the planets. Such definition is not properly fitted to Plutos. Pluto and it's satellite are look same and same in size and rotate on each other's axis and same revolve around the Sun. It couldn't be determined that which one is the planet and which one is satellite. Hence for the same reason, Pluto is removed from class of planet.

But according to Hindu astrology, the heavenly bodies, which are radiating light or reflecting light toward earth some how  and put effect on living thing of earth are called planets. The heavenly bodies due to whom rays toward earth is reaching or stopping rays to reach earth are called as planet. There will be a question, that most of heavenly bodies radiat light. Can those radiating bodies called as planet. Yes, can be called as planet but the rays comes from these planets doesn't reach to the earth, if reach doesn't put any effect to the life of living things on earth. Rays from Planets like Uranus and Neptune take too long time to reach earth and might be possible that sufficient amount of rays doesn't reach to earth surface. Hence Uranus and Neptune both are not considered under the astrological calculation. In some part of India, Uranus  is also considered for calculation.

In ancient time, earth is not considered as a planet. Because, as in Physics we have studied that the place from where an observer observe any thing is called as reference frame. Similarly, earth is considered as reference frame. Hence, earth is not considered as planet in astrological calculation and Sun and Moon both are considered as planet, even moon doesn't have its own light but it is radiated by Sun. Similarly like moon, other  planet doesn't radiate by their own but illuminated by Sun ray's reflection.

In modern science, there is no any planet like Rahu and Ketu. But in Hindu astrology, these two planets are considered under the astrological calculation. In Hindu astrology, these two planets are said as shadow planets. There is no physical existence of these planet. But a question come to our mind that, if these planets are shadow planet then whose shadow are called as Rahu and Ketu.

When Solar eclipse occur in sky, it is called in Hindu Mythology that Rahu planet engulf the whole Sun. You must know, how the event of Solar eclipse causes. According to modern science, when Sun, Moon and Earth comes in a straight line. The moon completely covers the Sun in day time and the shadow of Moon fall on earth. Due to this, severally darkness occur in day time during Solar eclipse on earth. Therefore, the shadow of Moon is called as Rahu.

Then we come to the shadow planet Ketu. When the event of Lunar eclipse causes in Sky, then Sun, Earth and Moon comes in a straight line and the earth cover up Sun completely. Then, the shadow of Earth falls on Moon and Moon look like hiding under the shadow even in full moon night. Therefore, the shadow of Earth is called as Ketu. A question rises in mind that,  are these shadows occur regularly in solar system. I will say yes. Because, these shadows not only occur on event of Solar eclipse or Lunar eclipse. If there is Moon and Earth, there must be shadow of these two. Hence, the shadow of Moon and Earth are considered under astrological calculation and considered as Shadow planet, named as Rahu and Ketu.

Related to the birth of Rahu and Ketu, a tale found in Hindu mythology that, during the churning of ocean known as Samudra manthan. By churning of ocean, a pot come out from ocean which was filled by eternal liquid (Amrut). If some one consumes this eternal liquid (Amrut). He will be eternal forever. Then deities decided, not to share this eternal liquid with demon. Other wise demon will be eternal and the whole universe will go toward the destruction due to demons. 

For this, Lord Vishnu incarnated himself as a lady to attract demons. Such a incarnation of Lord Vishnu is known as Mohin. Mohin take the Amruta pot and start to provide to deities and by some illusion, she provide liquor to demons in place of Amrut. Such a betrayal is get to know by a demon and he incarnated himself as deity and sit among the group of deities. 

Mohini was unknown about this and offered amrit to that demon. When that demon consume to neck area. Mohini cut the head of that demon. Head part of that demon became Rahu and Body part become Ketu. It's a mythological tale.

According to astrology (Shadow of Moon) Rahu gives opposite quality as compare to Moon. Moon is the plannet of mind, which gives positive thought. When the shadow of Moon (Rahu) give the negative thought. Shadow of earth (Ketu) give even more negativity than the Rahu. Rahu had consumed the Amruta. That why Rahu is placed in the group of deities and remain as eternal but never leave the quality of demon. Quality of Earth's shadow is also completly opposite to the earth. Earth provides life to creatures but Ketu (Shadow of Earth) destroys life.

Jai Mahakaal.

In any Hindu worship, Why filled water pot is worshipped first (Kalash Sthapan and Pooja)

During any religious ritual of Hinduism, a filled water pot with inverted coconut is placed near and worshipped. Many will question what is this and why such a filled water pot is worshipped. In approx 99% of Hindu ritual, filled water pot is worshipped.
Now I will explain, why it is worshipped and what is the reason to worship. Filled water pot is a symbolic form of mother earth and on its various part diifferent type of God are called and worshipped. Base of filled water pot signifies the grass land of earth, hence rice crop, paddy crop or maize crops are placed with some soil on the area, then after clay pot or any metal pots like silver, copper, brass etc is placed. Then water is completely filled up to the opening of clay pot which indicate that interior parts of earth having lots of water and mother earth has capability to store water. 

Opening part of filled water (Kalash) signifies the water reservoirs like ponds, rivers and wells where living beings consumes water for sustaining their life. A smallest part of mango tree with leaves are kept on filled water pot. This signifies for existence of longest tree on earth which are green and develop in the direction of sunlight, which is well known in botany as phototropism.Then a green coconut or inverted peeled coconut is placed on filled water pot which is the symbolic form of mountain on earth.
In Hindu ritual, placing and worshiping of filled water pot is called as "KALASH STHAPAN".

During placing of Kalash area by keeping some crop of rice, paddy aur maize, first mantra is chanted as "Bhu rasi, Bhumi rasi........." to worship supportness of mother earth (Adhara Shakti). During filling if water, seven holy rivers are called into kalasha with God Varuna (God of water).
Kalash is worshipped to enhance the "Dhara Shakti" means supportive power. Without supportive power, nothing can be happen. Without strengthening the base of a building, you can't built upper part of building. Hence, to get success in worship or anything, support power is to be worshipped first. This way mother earth is symbolically worshipped.

Thanks you

Concept of Rebirth in Shrimad Bhagwat Gita on the ground of Science

In Hinduism, 90% of Hindus believe that there is life after death, there is compulsory death after life. But many peoples will questioned that is there any proof on the basis of science. Concept of Rebirth of soul is well said by Lord Krishna in Holy book Shrimad Bhagwat geeta. When a person take birth, he must have to die. If a person die, then he has to birth. Such a cycle of life and death remain continuous. But many people reject to accept it and appeal that this not  true on basis of science.

      In science chapter of thermodynamic, we have studied a law that "Energy in the universe neither be created nor be destroyed but can be transformed from one form of energy to another form. In Bhagwat geeta same law is explained as "Soul never had birth any time in past nor will die any time in future, but every time soul hold a new body like changing of cloth". Every time body dies but soul remain as it is. Soul is eternal.

Here, I want say that when a living body do movement for any activity. It mean body has some energy and when body dies, no activity is performed by body. It meant body loss the energy. So directly we can say, soul in living body is a kind of energy. If the law of thermodynamic is true in basis of science. Then we also can  rebirth concept is also true.
In universe, everything has mass and on duration of time that mass body losses in the form of energy to the universe and returns back to existence in another mass form. According to Einstein's Law of relativity, everything that have mass, that thing must have energy.

Thank you

Jai Mahakaal
