Pragyanam Brahma which literally means Knowledge is Brahma. This is India`s ancient Hindu shastra rigved`s Mahavakya, in our four vedas one-one Mahavakya is mentioned.

That Gyan-Swarup Brahm is worthy of knowing and knowledge is beyond dignity. He is pure-form, intelligence-form, free-form and imperishable form. The same truth, knowledge and Sachchidananda-swarup are worthy of meditation. Only by meditating Mahtejaswi we can attain 'Moksha'. That divine being exists in all living beings. He is everywhere as Akhand-Bigrah. He always controls our mind and ego. By which the creature sees, hears, smells, speaks and tastes taste, it is wisdom. He is absorbed in all. That is 'Brahm.

This mantra is also the Mahavakya of Jagannath Dham or Govardhan Math, which is one of the Four Dham`s of India located in the east.
