There is no heaven or hell, only the heaven or hell you choose to create in this life and the karmic debt you will carry into the next life on earth. Your choices and actions in this life will decide what form you will return to this earth in. If you’re a good person and treat others well you might return as a happy-go-lucky person with few worries or cares, or perhaps as an eagle devoted to a life of soaring through the skies. If you’re a bad person and treat others badly, you may return as a cockroach or an “unlucky” person beset with strife.
This is life, this is your life. Are you who you want to be? Now, and the next time around? Life starts now, not tomorrow, not in the “next life,” and not whenever you’re ready. Now means now. Smile and be kind.
