Spiritual World: Characteristics of the Spiritual World

                            Q. What is the source of envy which brought us to this material world in the first place? I asked this question in one of our Sunday program and the speaker told me that there is no answer to this question. This really surprised me because I was thinking that Krishna could still be the source of the envy but yet unaffected by it. Just like 'maya' for which although Krishna is the source He is not affected by it. Please clarify.
