Introduction Introduction to Purusa


  • Purusa, a Sanskrit term, translates to "spirit," "self," or "consciousness."
  • It's a core concept in Sâmkhya philosophy, an orthodox school of Hindu thought.
  • Purusa is viewed as an eternal, unchanging, immaterial spirit.

Historical Context

  • Sâmkhya is one of the oldest dualistic schools of Hindu philosophy.
  • The concept of Purusa appears in ancient texts, including Jaina and Buddhist scriptures.
  • Although attributed to Maharshi Kapila, the exact timeline is uncertain.

Importance in Sâmkhya Philosophy

  • In Sâmkhya, Purusa is one of two independent principles, the other being Prakriti (nature or matter).
  • Purusa is all-conscious, all-pervasive, and motionless.
  • It serves as the witness-consciousness, contrasting Prakriti, which forms the phenomenal universe.

Preliminary Concepts

  • Purusa is often compared with Prakriti, the fundamental matter of the universe.
  • Prakriti is influenced by three gunas: sattva, rajas, and tamas.
  • The interplay between Purusa and Prakriti is crucial for the chain of evolution.

Objectives of Studying Purusa

  • Understanding the dualistic nature of reality in Sâmkhya philosophy.
  • Gaining insights into the eternal aspects of consciousness.
  • Exploring the Purusa-Prakriti relationship to grasp the nature of existence.

Conceptual Foundations of Purusa Definition and Nature of Purusa


  • Purusa is a complex term in Sâmkhya, often translated as "soul" or "consciousness."
  • It's considered the ultimate reality, distinct from the material world (Prakrti).
  • Purusa is beyond emotions, thoughts, and the external world.

Purusa and Consciousness

  • While Purusa is associated with consciousness, it extends beyond it.
  • In Sâmkhya, Purusa is the ultimate observer unaffected by emotions or external factors.

Purusa and Soul

  • Purusa differs from the soul in Western philosophy.
  • In Sâmkhya, the soul is part of Prakrti and mutable, while Purusa is the eternal, unchanging true self.

Theories of Origin

  • In Sâmkhya, Purusa has no origin; it's eternal.
  • Some texts suggest Purusa emerged from a cosmic egg.

Purusa in Ancient Texts

  • The Rigveda mentions Purusa as a cosmic being.
  • The Upanishads equate Purusa with ultimate reality or Brahman.

Relation with Prakrti

  • Sâmkhya is a dualistic philosophy, separating Purusa and Prakrti.
  • Although distinct, they interact to create experienced reality.
  • Understanding this distinction is key to liberation (moksha) in Sâmkhya.

The 25 Tattvas and Purusa The Hierarchy of Tattvas


  • Originating from Sâmkhya, Tattvas categorize existence into 25 elements.
  • Prakriti, in its base state, has three gunas: sattva, rajas, and tamas.
  • When disrupted, Prakriti evolves into 23 other Tattvas.

Purusa as the 25th Tattva

  • Defined as witness-consciousness, absolute, independent, and beyond perception.
  • In Sâmkhya, Purusa is the 25th Tattva and the experiencer.
  • It's free, beyond mind and senses, and indescribable.

Distinctions from Other Tattvas

  • Purusa is distinct from internal organs (Antahkaranas), organs of knowledge (Jnanendriyas), and organs of action (Karmendriyas).

Role in Liberation

  • Purusa serves as a witness-consciousness beyond perception.
  • Understanding Purusa's nature and distinction from Prakriti leads to liberation.

Interactions with Prakrti’s Tattvas

  • Contact with Purusa disrupts Prakriti's guna balance.
  • This leads to sensory experience and cognition.
  • Purusa experiences these manifestations, crucial in interaction with Prakriti's Tattvas.

Additional Contexts

  • Shuddhashuddha Tattvas in Shaivite and Shakta Tantric metaphysics.
  • Kashmir Shaivite Cosmology views Tattvas as stages of Involution.
