Sadhguru
Why is moksha preferred over heaven?
Life longs to be boundless
Something within a human being wants to expand limitlessly, which means it wants to be free. Heaven is just another place, with the same trouble after some time.
That is why in this culture the highest values established were mukti and moksha, meaning liberation or freedom, not heaven, because heaven is just another place, with maybe slightly better accommodation but the same trouble after some time.
