Material Energy: Material Conditioning

                                                                  Q. 1. I'm wondering how individual free will factors into the verses and purports describing the species of demoniac life. Specifically BG 16.19 - 20.

                                                                  Srila Prabhupada's purport states:
                                                                  "In this verse it is clearly indicated that the placing of a Particular individual soul in a particular body is the prerogative of the supreme will."

                                                                  "As for the demoniac, it is clearly said here that they are perpetually put into the wombs of demons, and thus they continue to be envious, the lowest of mankind."

                                                                  Q: BG 14-19 mentions that in all activities no other performer is at work other than the three modes. BG 13-21 similarly calls nature to be the cause of all material causes and effects. I have difficulty understanding this. Does it mean that inert matter is the cause, or does it refer to the controlling deities in charge of different departments of nature?
                                                                   
                                                                   
                                                                  Material nature consists of the three modes. The material nature or the material energy works under the direction of the Supreme Personality of Godhead, Sri Krishna.
                                                                   

                                                                  Q: Although I heard in different classes about the temporary nature of this body and associated attachments and relations, when it comes to practicality I forget everything and act in a very unpleasing way, for which I regret very badly later. Could you kindly explain me how is it possible to remember this at the very unpleasant situations and apply practically and take shelter in such difficulties?

                                                                   

                                                                  Without being attached to Krishna, we will be attached to the temporary. Asat-trsna means 'thirst for the impermanent'.

                                                                  This 'thirst' comes from the contaminated subtle body. Jiva Goswami calls this the 'antahkarnah'. See the below for explanation; association with and hearing from sadhus is the means to overcome this contamination:

                                                                  Q. Will there be always some souls for in this material world or will there be a moment in eternity when there won't be any material world. For I heard that for the ompleteness of Lord Krishna there is need for material world.
