The seat of thoughts is the mind. The mind has been described as symbolizing the form of Vishnu. Vishn means one who pervades everything. The mind has the power to reach out for anything in the universe. Hence, the cosmos is rooted in the mind.
The thoughts emanating from the mind find expression in words or speech. Thus, the heart, the mind and the speech together constitute humanness. Sanctifying these three has been described as "Trikaranasuddhi", purity in thought, word and deed. The worship of the Trinity really calls for purification of the mind (Vishnu), the heart (Easwara), and speech (Brahma). Men today are immersed in transient, worldly activities. They should sanctify all actions by purifying their feelings.
