Samkhya is one of the six major schools of Hindu philosophy, and it is based on the concept of dualistic realism between Purusha (spirit) and Prakriti (matter). This philosophy is primarily concerned with understanding the nature of reality and the human experience. The main texts of Samkhya philosophy are the Samkhya Karika and the Samkhya Sutra.

The Samkhya Karika, also known as the Samkhya Pravachana Sutra, is the foundational text of Samkhya philosophy. It was written by Ishvara Krishna in the 3rd or 4th century CE and consists of 72 verses organized into six chapters. This text provides a detailed explanation of the fundamental principles of Samkhya philosophy, including the concept of Purusha and Prakriti, the three gunas (qualities), and the 25 tattvas (categories of existence).

The Samkhya Sutra, also known as the Samkhya Pravachana Sutram, is another important text of Samkhya philosophy. It was written by Kapila, the founder of Samkhya, and consists of 526 sutras organized into six chapters. This text is considered to be the most authoritative and comprehensive treatise on Samkhya philosophy. It elaborates on the principles outlined in the Samkhya Karika and provides a detailed analysis of the nature of reality and the human experience.

Apart from these two main texts, there are also other important texts that further expound on Samkhya philosophy. These include the Tattva Samasa, Samkhya Tattva Kaumudi, and Samkhya Tattva Viveka. These texts provide additional insights and commentary on the principles of Samkhya and are considered to be valuable resources for understanding this complex philosophy.

In addition to these traditional texts, there are also modern interpretations and commentaries on Samkhya philosophy. Swami Vivekananda, a renowned Hindu monk and philosopher, has written extensively on Samkhya in his book "Raja Yoga." Other modern scholars and practitioners have also contributed to the understanding and development of Samkhya philosophy.

In conclusion, the Samkhya Karika and the Samkhya Sutra are the main texts of Samkhya philosophy. These texts provide a comprehensive and detailed explanation of the principles and concepts of this dualistic realist philosophy. They continue to be studied and revered by scholars and practitioners alike, making a significant contribution to the understanding of the nature of reality and the human experience.
