What is this world, after all?
It is nothing but the materialisation of the thought-forms of Hiranyagarbha or God.
You have got waves of heat and light and electricity in science.
There are also thought-waves in Yoga. Thought has tremendous power. Everybody is experiencing the power of thought unconsciously to a greater or lesser degree.
Great Yogins like Jnanadev, Bhartrihari and Patanjali used to send and receive messages to and from distant persons through mind-telepathy (mental radio) and thought-transference. Telepathy was the first wireless telegraph and telephone service ever known to the world.
Just as you take physical exercises, play games such as tennis and cricket in order to maintain physical health, you will have to maintain mental health by radiating the right thought-waves, by taking Sattvic food, mental recreation of an innocent and harmless nature, change of mood, relaxation of mind by entertaining good, ennobling and sublime thoughts and by cultivating the habit of cheerfulness.
Every thought that you send out is a vibration which never perishes. It goes on vibrating every particle of the universe and if your thoughts are noble, holy and forcible, they set in vibration every sympathetic mind.
Unconsciously all people who are like you take the thought you have projected and in accordance with the capacity that they have, they send out similar thoughts. The result is that, without your knowledge of the consequences of your own work, you will be setting in motion great forces which will work together and put down the lowly and mean thoughts generated by the selfish and the wicked.
Thoughts Are Finer Forces
Thought is a finer force. This is supplied to us by food. If you read Chhandogya Upanishad – the dialogue between Uddalaka and Svetaketu – you will understand this point well.
If the food is pure, thought also becomes pure.
He who has pure thoughts speaks very powerfully and produces deep impression on the minds of the hearers by his speech.
He influences thousands of persons through his pure thoughts. A pure thought is sharper than the edge of a razor. Entertain always pure, sublime thoughts. Thought-culture is an exact science.
Those who harbour thoughts of hatred, jealousy, revenge and malice are verily very dangerous persons.
They cause unrest and ill-will amongst men.
Their thoughts and feelings are like wireless messages broadcast in ether, and are received by those whose minds respond to such vibrations.
Thought moves with tremendous velocity. Those who entertain sublime and pious thoughts help others, who are in their vicinity and at a distance also.
Thought has got tremendous power. Thought can heal diseases. Thoughts can transform the mentality of persons. Thought can do anything. It can work wonders. The velocity of thought is unimaginable. Thought is a dynamic force. It is caused by the vibrations of psychic Prana or Sukshma Prana on the mental substance.
It is a force like gravitation, cohesion or repulsion. Thought travels or moves.
