The Yogic Sukshma Vyayama is a series of exercises that are preparing our body for the higher practices of Yoga. 

Without proper preparation, Yoga can cause imbalances and even injuries. One should not undertake any Yoga practice without preparing oneself properly. First of all, we have to adopt an adequate lifestyle. The Yogic Sukshma Vyayama, if practiced daily, is improving our health tremendously and helps us to establish an equilibrium inside our bodies. Without the practice of these exercises, one should not engage in Yoga practice, at all. In this video, you can see a short demonstration of the Yogic Sukshma Vyayama by Dhirendra Brahmachari, unfortunately, this clip does not contain the whole series of exercises. For the complete Sukshma Vyayama see the Online course section or follow this link:

Besides these subtle yogic exercises, we also have to adopt a certain diet, the right attitude towards life and undergo certain cleansing techniques, the Shat Karmas. See the links above for more information about these topics.
