Hinduism...Aren't Vaikuntha, Brahmalok, Shivalok, Indralok etc imaginary abodes?

We often say to others that so and so is my ultimate destination? But other than in books, where do these abodes exist? There is no human being in the entire world who has seen such abodes, even enlightened souls have not seen it. Then why do we talk about it and eye wash youngsters into believing myths?

What is imagination ? even whole cosmos is imagination of god !!

these Lukas are not mere imaginations and it is wrong to say no one has seen them. These are different Astral Planes, where souls work out their subtle karma, before taking re-birth or before merging into the supreme

Which way it matters my friend, do you think youngster are to stupid to believe myths? i don't believe anything like this but i do have the guts to find it out myself so unless one has the ability to find it out,there is no use in contradicting others belief.

Those abodes are not some imaginary planes but physical Lukas. Acc. to Vedas, the ya ma Lola is about 200 billion miles south of Mandara mount. (may be the galacticALenter ??) We are trained to scientific standards of Cosmos/metrics , that It is just that we dont know the correlation to Rishis Sankrit Cosmic/names. But whatever most understood, they could figure out the similar measures. Their intuition were not wrong! Also, the planetary rotation/axis/origin/age/nature are almost in close proximity to science. The svaha/swar loka spans from Sun which moves (axially) towards the North pole (Dhruva, being the tail of saptarishi/small dipper, Vishnu leads these solar systems further...Rig Veda), which is completely fascinating....

[From the link, Just calculate the space till the satyloka. ..]

In the link above, you may find these lines,
'"The world is encompassed on every side and above and below by the shell of the egg of Brahm?" - I understand this as a finite universe. "Around the outer surface of the shell flows water, for a space equal to ten times the diameter of the world" - Reasonable guessing may be, this represents the milky ocean where lays the Vishnu and Brahma prays/meditates to Him on its Shore/Satya-lokam, for all the problems of Creation. Beyond these layers is the Vaikuntam/not affected by material creation. These 7 lokas, elements, ether(self) also said to represent our body.

They were not lying and have actually realized them!! They didn't have hubble telescopes or used kepler's equations.

E:G: In ancient Indian astronomy, the Surya Siddhanta, an Indian astronomical text of the 5th century, estimates the diameter of Mercury as 3,008 miles, an error of less than 1% from the currently accepted diameter of 3,032 miles. Buddha is the son of Moon and a star Rohini, Mercury surface/nature is similar to Moon...

Men with a poor fund of knowledge only accept the history of the world from the time of Buddha, or since 600 B.C., and prior to this period all histories mentioned in the scriptures are calculated by them to be only imaginary stories. That is not a fact. All the stories mentioned in the Pur?n?as and Mah?bh?rata, etc., are actual histories, not only of this planet but also of millions of other planets within the universe. Sometimes the history of planets beyond this world appear to such men to be unbelievable. But they do not know that different planets are not equal in all respects and that therefore some of the historical facts derived from other planets do not correspond with the experience of this planet. Considering the different situation of different planets and also time and circumstances, there is nothing wonderful in the stories of the Pur?n?as, nor are they imaginary. We should always remember the maxim that one man's food is another man's poison. We should not, therefore, reject the stories and histories of the Pur?n?as as imaginary. The great rs is like Vy?sa had no business putting some imaginary stories in their literature's.
