When the personal individuality is attuned to universal being, it is the condition of Yoga. The individual begins with the body, but there are many things within the body, as there are in the physical cosmos. There are Prana, senses, mind, intellect, etc., encased in the body. All these things within have to be in gradual union with the universal. The mind cannot be so attuned when the body is in revolt.
Yoga requires union of everything in the personality with the universal.
Asana is the initial step in Yoga, whereby the bodily structure is set in unison with the cosmos. When an individual thinks in terms of the ego, which is self-affirmation, with a selfish attitude towards the things of the world, there is internal disharmony. The more is one unselfish, the more also is one concordant with reality, and the more is the selfishness, the more also is the discordant note struck in one s life. Yoga is a systematized process of establishing permanent friendship with Nature in all its levels,-friendship in the physical, vital, mental, intellectual and spiritual levels. It is all love and friendship, and no enmity anywhere.
