“Thought is a vital, living force, the most vital, subtle and irresistible force that exists in the universe. The thought-world is more real relatively than this physical universe. Thoughts are living things. 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.
Mind assumes the form of anything it contemplates. When you think of an object, your mind shapes itself into the form of that object. When you change your thought, your mind also changes its shape. Many modifications continually arise in the mind. Your thoughts rapidly change. Your mind also changes its shape rapidly. Every moment, mind is continually creating hundreds of these thought-forms and continually dispersing them again. It never holds on steadily to one thought-form for some time.
Every thought has a certain name and a certain form. Form is the grosser and name the finer state of a single manifesting power called thought. But, these three are one. It is the unity in trinity, the three degrees of existence of the same thing. Wherever the one is, the others also are there. Suppose your mind is now perfectly calm, entirely without thought. Nevertheless, as soon as thought begins to rise, it will immediately take name and form. Thus you find that every idea that man has, or can have, must be connected with a certain word as its counterpart.
Language is different, but thought is one. Mental image is the same in all. Sound has got four forms, viz., Para, Pasyanti, Madhyama and Vaikhari. Vaikhari is the ordinary speech. It differs in different countries. But Para, Pasyanti and Madhyama are one and the same. Para is undifferentiated sound that lies dormant in Brahman.”
