Patanjali's Yoga Sutras is a foundational text of Yoga philosophy, composed by the sage Patanjali around 200 BCE. It consists of 196 aphorisms that outline the principles and practices of yoga, emphasizing the importance of mental discipline, ethical conduct, and meditation for achieving spiritual growth and self-realization. The text is divided into four chapters: Samadhi, Sadhana, Vibhuti, and Kaivalya. Each chapter addresses different aspects of the yogic path, including the nature of consciousness, the practice of meditation, and the ultimate goal of liberation. The Yoga Sutras serve as a guide for practitioners seeking to deepen their understanding of yoga and its transformative potential.
