Your next question was about the free will, whether we have it or not? If one is not intelligent enough for making for making decisions, then all decisions shall be sanctioned by the spiritual master. Neophyte means no independent decisions, no free will, that means surrender. But when he is trained up then automatically he gets his freedom. Just like a small child can only eat such things which are sanctioned by his parents, not by his own discretion. Free will is that when the controller says do this, you can use your free will to do it or not to do it. You have got the power to not do:
- iti te jnanam akhyatam guhyad guhyataram maya
- vimrsyaited asesena yathecchasi tatha kuru
- (BG 18.63)
"Thus I have explained to you the most confidential of all knowledge. Deliberate on this fully, and then do what you wish to do." (BG 18.65)
Krishna asks, "Have you decided to fight?" "Yes, I have decided to follow Your order." This is free will.
