Q: Where and how thoughts are formed, do they come from the subtle body?
ALOKDA: The origin of thoughts is far above like lightnings in the sky. They are rays of light that come to earth as vibrations to awaken earth and man to consciousness. But just as the rays get mixed with the mud and assume a muddy character so too these thought rays when they enter the cosmic field assume a triple character of good-bad-neutral vibrations. From the cosmic field they enter into all things as a dumb knowledge. In human beings they enter the brain and pick up the language, words and sounds to which the person is conditioned and express themselves through speech. Therefore, by training the speech, by cleansing the thoughts freeing them from all the mud and filth into which these brilliant rays are trapped we can ascend upwards as through a rope, right up to their original Source.
The thoughts therefore can be divided into two types with reference to their origin. First two closely connected to the original vibration of Light are in the higher mental worlds in a subtle form and are called paravak and pasyanti, the supreme word and the seeing word. Then when they enter our realm and get modified by the ignorance they are called madhyama and vaikhari, where vaikhari is the average human though and speech.
