If we throw a piece of stone in a tank or a pool of water, it will produce a succession of concentric waves travelling all around from the affected place. The light of a candle will similarly give rise to waves of ethereal vibrations travelling in all directions from the candle. In the same manner, when a thought, whether good or evil, crosses the mind of a person, it gives rise to vibrations in the Manas or mental atmosphere, which travel far and wide in all directions.
What is the possible medium through which thoughts can travel from one mind to another?
The best possible explanation is that Manas or mind-substance fills all space like ether and it serves as the vehicle for thoughts, as Prana is the vehicle for feeling, as ether is the vehicle for heat, light and electricity and as air is the vehicle for sound.
The Ether of Space Registers Thoughts
You can move the world through thought-force. Thought has great power. It can be transmitted from one man to another man.
The powerful thoughts of great sages and Rishis of yore are still recorded in the Akasa (Akasic records). Yogins who have clairvoyant vision can perceive those thought-images. They can read them.
You are surrounded by an ocean of thought. You are floating in the ocean of thought. You are absorbing certain thoughts and repelling some in the thought-world. Everyone has his own thought-world.
Thoughts are living things. A thought is as much solid as a piece of stone. We may cease to be, but our thoughts can never die. Every change in thought is accompanied by vibration of its matter (mental).
Thought as force needs a special kind of subtle matter in its working. The stronger the thoughts, the earlier the fructification. Thought is focussed and given a particular direction and, in the degree that thought is thus focussed and given direction, it is effective in the work it is sent out to accomplish.
Thought excels light in speed
While light travels at the rate of 1,86,000 miles per second, thoughts virtually travel in no time. Thought is finer than ether, the medium of electricity.
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 lightning speed in all directions and enter the minds of persons and produce in them also similar thoughts of harmony and peace.
Whereas a worldly man whose mind is full of jealousy, revenge and hatred sends out discordant thoughts which enter the minds of thousands and stir in them similar thoughts of hatred and discord.
