From the Introduction:

"In the beginning of Jnana Yoga, after the mind is made completely calm and objectless, the Yogi receives the first glimpse of the Self, as ever expanding effulgent consciousness imbued with joy. As the meditation itself deepens, in this or in some future existence, the Self is realized in its absolute perfection. Thus, man the Self, meditating on the Self, realizes himself as pure Consciousness-Existence-Bliss Absolute."
