Jai Sri Ganesha,
The dwellers of heaven get immortality is half a truth,
Those who attain to immortality attain the spirit to enter heaven in truth with self,
Three kinds of heaven could be visualized in truth with the scenario,
One heaven exists on the pitch of the mind, the second is a region enriched with the truth of blissful unison for spirit, and heaven exists above the horizon of both for an enlightened spirit to have interaction with self at that orientation of truth and the cause,
May lord bless all,
Thanks, please
