When we came to this world, the first thing we did was we took a deep breath in, and then we started crying. And the last thing we will do in this life is breathe out, and then others will cry.
If we don’t make others cry, then we have not lived a good life.
When the soul leaves the body with full contentment, with a lot of love and wisdom, then it is not compelled to come back. It can come back on its own will.
