The emptiness, silence and peace are the basic condition for the spiritual siddhi – it is the first step towards it. It enables the Purusha to be free from the movements of Prakriti, to see and know where they come from since they no longer rise from within the mind, heart etc., these being in a state of quietude, and to reject the lower movements and to call in the knowledge, will etc. of the higher Consciousness which is above.
