As is in Shri Sai Satcharita, by Hemadpant .. Chapter XXX Page 160, 161

Om Sai Shri Sai Jaya Jaya Sai

Unless the Saint wills it, no one is able to go and see him?  Even the leaf of the tree won't move, without his bidding.  The more anxious a Bhakta is for the visit to the Saint, the more devout and faithful he is, the more speedily and effectively is his wish satisfied to his heart's content. 

Bow to Shri Sai - Peace be to all
