“Thought is very contagious, nay, more contagious than the Spanish Flu. Thought moves. It actually leaves the brain and hovers about. It enters the brains of others also. A sympathetic thought in you raises a sympathetic thought in others with whom you come in contact. A thought of anger produces a similar vibration in those who surround an angry man. It leaves the brain of one man and enters the brains of others who live at a long distance and excites them. A cheerful thought produces cheerful thought in others. A thought of joy creates sympathetically a thought of joy in others. You are filled with joy and intense delight when you see a batch of hilarious children playing mirthfully and dancing in joy.
In broadcasting, a singer sings beautiful songs at Calcutta. You can hear them nicely through the radio-set in your own house at Delhi. All messages are received through the wireless. Even so, your mind is like a wireless machine. A saint with peace, poise, harmony and spiritual waves sends out into the world thoughts of harmony and peace. They travel with tremendous lightning speed in all directions and enter the minds of thousands and produce in them also similar thoughts of harmony and peace. Whereas a worldly man whose mind is filled with jealousy, revenge and hatred sends out discordant thoughts which enter the minds of thousands and stir in them similar thoughts of hatred and discord.
Thought is very contagious. Keep a good and honest man in the company of a thief. He will begin to steal. Keep a sober man in the company of a drunkard. He will begin to drink.”
