Ethics, philosophy and mysticism blend in a wholesome perennial form of wisdom in this work, which may be said to be a continuation of the wisdom of prehistoric India, more or less independent of the Vedic tradition.

Creation, before Brahma gave it the four directions, symbolized by his four heads, has the indefinite nature of all-pervading water ("God moved upon the face of the waters" as Genesis, 1, 2, puts it) on which the numinous principle of life or creation was supposed to recline. This image of creation formed the background of the later Vishnu tradition which itself suffered many changes through history and become the Vasudeva cult of the Bhagavata.

Yoga: Harmonization. In all organic structuring of organisms, two opposite principles are employed, such as the psychic and somatic, the chemical and electrical, the sensory and the motor, the sympathetic and parasympathetic. In the functional aspects also we see such complementarities which can also prove to be contradictories if the law of harmonization is not properly maintained. Numbers of functions in the body are autonomous, regulated by the opposites of control and release. The principle of harmonization is very much like a principle of ambivalence going from plus to minus and arriving at a neutral point of homeostasis. The overall science dealing with this is Yoga - always with a middle ground. There are many levels of finding such homeostasis, such as between the spiritual and the social, in which the middle ground is morality; crime and punishment in which the middle ground is therapeutic correction. A similar ambivalence is between the psychological and physiological, in which the middle ground is awareness of harmony and a sense of ease.
There are different systems of Yoga in India. Some contemporary systems are: Patanjali's Yoga Sutras, based on the Samkhyan epistemology called Samkhya Pravachana Sutras; two other moderate systems which are the sapta-bhumika-Yoga of the Yoga-Vasishta, and the Yoga of karma Yoga and karma sannyasa-Yoga. Two complementary systems founded by Yogendra and Matsyendra are today called Hatha Yoga.
