There is the prayer of the heart. There is a mental prayer. There is an oral prayer. There are many forms of prayers. Some prayers go by the name of meditation. The prayer of a man of knowledge consists in a constant and continuous awareness that God is immanent in all the universe, that God is the basis and the background of all that is manifest and existent.

Therefore, the wise man, the man of superior knowledge, the man of divine Knowledge, prays by way of his continued inner mental awareness of God everywhere. In all that is limited, he is
conscious of the Unlimited. In all that is changing, he
perceives the Unchanging. In all that is perishing, he
discovers the Imperishable. He knows that every
moment of time is being supported by the Timeless.
He penetrates into the phenomenon of life and
discovers therein the seeds
of the immortal Life. This is
his prayer, his form of reflection,
his type of dynamic and operative
knowledge. That wise man whose
intelligence touches the infinite and the absolute
Principle wherever it is operating, can be best
described as a man of prayer.
