Wisdom of today.

A realized man, it says, becomes nearly mad (intoxicated with joy), actionless and Self-Satisfied (his own self having merged with the Self). Such a devotee starts experiencing the instinctive movements like weeping, singing, laughing, jumping, dancing, trembling, clapping, composing poems, adopting a number of Hatha Yoga postures, Pranayam, Mudras (pose, posture or gesture), hearing internal sounds and seeing internal visions. He may shed tears, fall on the ground motionless; his body may become light, heavy, cool or warm without any physical reason.

Ordinary human beings may think that he has gone mad but he derives pleasure in all these activities.
