In that context, we talk of two different disciplines, one is physics and the other is philosophy. That is also the reason why where physics ends and is not able to move any further, philosophy starts. In order that you may understand and you may realise this aspect of , you have to do some exercises and you have to go through some practices. If you want to do that through your sense perceptions, through your mind and through your intelligence or, in the analogy, if you want to convert milk into curds, curds into butter, butter into buttermilk, naturally you have to adopt some accepted and standard procedures and you have to apply them in the proper manner. If you do not know the procedures of converting them or if you do not apply those procedures properly, you cannot convert milk into curd or curds into butter or butter into buttermilk. In every act of ours, we should not forget the goal or what our destination is. In this analogy, the original source is milk and everything else - curds, butter and buttermilk - are only things that have come out of the source, namely the milk, by some kind of change that has been introduced.
