Book II: Sadhana Pada

Book 2, Sadhana Pada contains 55 sutras. Sadhana is the Sanskrit term for "practice" or "discipline," aiming at preparing and calming the mind. Here the author outlines two systems of Yoga: Kriyā Yoga and Aṣṭāṅga Yoga ('Eightlimbed Yoga'). Both are outer or preparatory aspects, which precede the true aim of yoga, namely the development of one-pointedness and samadhi capable of the discriminative discernment of the Seer (consciousness) from the objects desires of common consciousness.
