Isvarakrishna was an Indian philosopher who lived during the 5th century BCE. He was a prominent figure in the Samkhya tradition of Hindu philosophy, which emphasized the duality of purusha (consciousness) and prakriti (nature).
Isvarakrishna is known for his work, the Samkhya Karika, which is considered one of the most important texts in the Samkhya tradition. In this text, he outlines the concept of purusha and prakriti and their relationship to one another. He also discusses the concept of purusha-prakriti vikara, which refers to the transformation of prakriti into the material world we experience.
Isvarakrishna also believed in the concept of avidya, or ignorance, which he saw as the root cause of suffering in the world. He believed that by gaining knowledge and understanding of the true nature of reality, one could transcend suffering and achieve liberation.
Overall, Isvarakrishna’s contributions to the Samkhya tradition have had a lasting impact on Hindu philosophy and continue to be studied and debated by philosophers today.
