rapids are the five pains, it has fifty kinds of sufferings, and five branches." Adi Shankara and other scholars have explained, using more ancient Indian texts, what each of these numbers correspond to. For example, the five streams are five receptive organs of a human body, the five waves are the five active organs of a human body, and five rapids are the major health-related life stages. The subject of meditation, states Shvetashvatara Upanishad, is the knower and the non-knower, the God and non-God, both of which are eternal. The text distinguishes the highest Self from the individual Self, calling the former Isha and Ishvara, and asserting it is this Highest Brahman which is Eternal and where there is the triad - the bhoktri (subject), the bhogya (object), and the preritri (mover).

Such knowledge and ethics is, asserts the Upanishad, the goal of Upanishad. Yoga as means for self knowledge, self discipline – Second Adhyāya The second Adhyaya of Shvetashvatara Upanishad is a motley collection of themes. It begins with prayer hymns to God Savitr, as the rising sun, the spiritual illuminator and the deity of inspiration and self-discipline. Thereafter, the Upanishad discusses Yoga as a means for self-knowledge. The verses 2.8 and 2.9 describes yoga as state of body and mind, wherein the body is in threefold erect posture, and mind along with
