The great sage Patanjali, who was considered an authority on yogic science, affirmed in the Yoga Sutras that yoga is natural. The first aphorism of Patanjali’s Yoga Sutras says, “Atha yoga anuśāsanam“. In Sanskrit, śasanam means “commandment.” The prefix anu means it is a commandment given by another, in this case by the Divine, Nature, or the Eternal Truth. The Yoga Sutra is an enlightened text which explains yoga in detail. It contains four chapters on Samadhi, different devices to attain Samadhi, different achievements (siddhis) on the path, and Realization. This unique text, in the form of aphorisms, contain many hidden layers, and aspects of Yoga. The truly knowledgeable and experienced may understand these layers. This text is an important doorway in understanding yogic disciplines, an ideal yogic lifestyle, and other wings of knowledge established by yogis.
