Hi: Most people know that Hindus believe that we might come back as lower life forms - bugs, animals
I want to correct some misconceptions on this issue
First, these ideas were not limited to Hindus alone - we don't do that - We are ALL God's Children and His/Her rules apply equally to ALL of us
Second, most religions view God as a Master - reward(Heaven) & punishment(Hell) is how he operates. Hindus view God as a Parent/Teacher - a Parent/Teacher instructs, Teaches but does not punish
So, being reborn as a Dog or a cat is not a punishment but a Choice that we made of our own free will
Thru Life God has taught us that we get to stay in the nest - fed, protected, sheltered & cared for - for only a little while. We can't stay a child forever - we have to move out of the nest, grow up, learn to stand on our own two feet, make a living and face the world on our own. Not just us, but ALL life forms on this earth obey this law
Heaven contradicts this law - it says we can run back to our childhood and this time stay there forever - God will be our Nanny - He will feed, protect, shelter and care for us - zero work, no responsibilities or worries, just like what we had in childhood. But God did not create Heaven or Hell - Religions did
But God is not cruel - those who seek heaven are sending a clear message to God - Life is too tough for them - they want an easier life & that is EXACTLY what they WILL get
As a Dog or a cat - as a pet - they will get the easy life of Heaven - their master will feed, protect, shelter and care for them - zero work, zero responsibilities - Dogs can just lie about all day!

Careful what you wish for, it will come true
