One day Shashi noisily ripped a piece of cloth in the Master’s presence, startling him. Because of Ramakrishna’s experience of oneness, when the cloth was being torn, he felt as if his own chest were being torn as well. When a person is highly spiritually evolved, his physical and mental systems become very sensitive. The Master did not like his disciple’s rough action, so he said to him: “What are you doing? Never tear the cloth in that way. The serpent power [kundalini shakti], which is within me, may snap at you. Be careful.” (Source: God Lived with Them)
