sidhi sadhana , the sidha vidya 

and one must learn this and master it 

Shakespear had said "what ever a human mind can think that is possible"
.......yadbhaavam thath bhavathi, 

" ख़ुदी को कर बुलंद इतना कि हरतक़दीर से पहले

ख़ुदा बंदेसे ख़ुद पूछे बता तेरी रज़ा क्याहै

 "
.......yatheenam brahma bhavathi sarathi 

this is the clue on how ''miracles '' are made to happen 

it is possible to reach a level where thoughts materialize , things happen as per one's wish, god becomes the servant of bhaktha 

this is the level of sidha , the ability to cognize the thoughts at the point of their origin, the field of pure consciousness which is the field of all possibilities, chethana sarva sidhi pradayini
