The extraordinary postures into which Maharajji placed his body were no more random than anything else he did.
Some of his older devotees got quite proficient in reading Maharajji's body language, for many of the positions were actual mudras(statements in form) that gave blessings, activated certain powers, or brought about certain changes in the environment.
Siddhi Ma was holding a picture of Maharajji in which he is lying on his side, a classic pretzel, with one hand on top of his head.
She said that this mudra of hand on top of head means : "Don't worry about anything. I've got everything under control."
