The Bodhisattva is said to have well grasped the teachings of the Tathagatas when, all alone in a lonely place, by means of his Transcendental Intelligence, he walks the path leading to Nirvana. Thereon his mind will unfold by perceiving, thinking, meditating, and, abiding in the practise of concentration until he attains the “Turning About (पूर्ण परिवर्तन )” at the source of habit-energy, he will thereafter lead a life of excellent deeds. His mind concentrated on the state of Buddhahood, he will become thoroughly conversant with the noble truth of self-realisation; he will become perfect master of his own mind; he will be like a gem radiating many colors; he will be able to assume bodies of transformation; he will be able to enter into the minds of all to help them; and, finally, by gradually ascending the stages he will become established in the perfect Transcendental Intelligence of the Tathagatas.
Nevertheless, Transcendental Intelligence (Arya-jnana) is not Noble Wisdom (Arya-prajna) itself; it is only an intuitive awareness of it. Noble Wisdom is a perfect state of imagelessness; it is the Womb of “Suchness”; it is the all-conserving Divine Mind (Alaya-vijnana) which in its pure Essence forever abides in Perfect Patience and Undisturbed Tranquility.
