Acharya Prashant provides a comprehensive explanation of Ashtanga Yoga, defining it as a technology designed to facilitate the union of the mind with its source. He begins by detailing the first limb, Yama, which focuses on prohibitions or what one must stop doing. He emphasizes that the path to self-development starts with ceasing current false actions rather than starting something new. Within Yama, he explains non-violence as a form of self-love and energy, truth as avoiding the dangerous lies that masquerade as reality, and non-stealing as the realization that everything we identify with is actually 'other' or accidental. He further clarifies celibacy as living in constant remembrance of the vast basis of existence, and forgiveness as the state of never being hurt by the ego. He also discusses steadfastness, compassion, simplicity, moderate living, and purity as essential components of Yama. Moving to the second limb, Niyama, Acharya Prashant describes it as the set of practices to be followed. He redefines penance as pure awareness or a 'mutation' brought about by observation rather than guilt. Contentment is described not as a compromise, but as the overwhelming feeling of having received so much that nothing more can be asked for. He explains charity as the sharing of one's own joy and light, and theism as the inherent power to know and be aware. He distinguishes between the Absolute and the Creator, defining the latter as the principles governing the world. The discourse concludes with explanations of spiritual study, intelligence as awareness-led mental activity, vows as the commitment to remain firm, and repetition as a necessary alarm clock for the mind. Finally, he defines austerity as the 'flame of attention' that burns away all that is false and non-essential.
