The Yoga Sutras of Patanjali is a foundational text in the practice and philosophy of yoga, composed by the sage Patanjali around the 2nd century BCE. The work is a collection of 196 aphorisms or sutras, which are concise statements designed to convey complex philosophical ideas in a succinct and memorable form. The sutras are divided into four chapters each addressing different aspects of yoga practice and philosophy namely:

1. Samadhi Pada (Chapter on Concentration): This chapter outlines the goals of yoga and introduces the concept of Samadhi, which is the state of meditative absorption where the practitioner merges with the object of meditation. It describes the different levels of concentration and the initial steps in the path of yoga.

2. Sadhana Pada (Chapter on Practice): The second chapter focuses on the practical aspects of yoga and introduces the eight limbs of yoga (Ashtanga Yoga), which are a comprehensive guide to living a yogic life.

3. Vibhuti Pada (Chapter on Powers): This chapter delves into the supernatural powers (siddhis) that can arise from intense practice and deep meditation. It explains how these powers should not be the goal of yoga but rather potential distractions on the path to enlightenment.

4. Kaivalya Pada (Chapter on Liberation): The final chapter discusses the nature of liberation (kaivalya) and the realization of the true self. It explores the philosophical underpinnings of yoga and the ultimate goal of spiritual freedom and self-realization.

The Yoga Sutras of Patanjali are revered for their depth and clarity in elucidating the path of yoga through concise and profound aphorisms. They provide a structured framework for understanding the mind, the nature of human suffering, and the means to attain spiritual liberation. Below you can find the chapters and their meanings:
