Principles in Indian Metaphysics refer to the foundational philosophical concepts that explore the nature of reality, existence, consciousness, and the ultimate truth as understood in various Indian philosophical traditions. Rooted in ancient scriptures like the Vedas, Upanishads, and later schools such as Vedānta, Sāṃkhya, Yoga, Nyāya, and Buddhism, Indian metaphysics delves into questions about the self (Ātman), the universe (Brahman), causality (Kāraṇa), and liberation (Mokṣa). These principles aim to transcend empirical understanding and provide a deeper, spiritual framework for interpreting existence and human experience. Various principles are outlined from Indian metaphysical perspectives:
- Principle of Truth (Satya): Something "unchangeable, indestructible, eternal, and immutable." Only Brahman is ultimately satya. Three levels of truth (satta) are identified by Sankara: pratibhasika (illusory), vyavaharika (empirical), and paramarthika (absolute).
- Principle of Knowledge (Jnana): Human knowledge is an undeniable fact, as "I know that I know."
- Principle of Meaning (Sphota): Every linguistic unit is a "single meaningful, eternal, and formal symbol" from which meaning bursts forth.
- Principle of Negation (Abhava): Thought starts with negation when life is obstructed.
- Principle of Assertion or Affirmation (Pratipada): Every negation implies an affirmation on which it rests. Being is the "ever unnegated and unnegatable Being."
- Principle of identity (tattvamsi): The identity of the individual self with Brahman.
- Principle of distinction (bheda): Distinctions exist, including heterogeneous, homogeneous, and internal distinctions.
- Principle of contradiction (virudha): Two contradictory statements about the same object under the same respect cannot both be true simultaneously.
- Principle of exclusion (apoha): A word expresses meaning by excluding its opposites.
- Principle of fullness (purnam): Fullness comes from fullness; subtracting fullness from fullness leaves fullness.
- Principle of order (rta): The universe has an "ordered universe by rta," the "immanent law of things."
- Principle of presumption (arthapatti): Assuming an unperceived fact to explain inconsistent facts.
- Principle of momentariness (kshanika): Everything changes from moment to moment, and existence is a "constant flow."
- Principle of indescribability (sunya): Something that is "indescribability (avachya or anabhlabya)" and transcends the categories of the intellect.
- Principle of creative-power (maya): The "real power-principle by which the world is created," making the indeterminate Brahman determinate.
- Principle of indeterminate and determinate (nirvikalpaka evam savikalpaka): Two kinds of perception: mere acquaintance (nirvikalpaka) and predicative knowledge (savikalpaka).
- Principle of liberation (moksha): Beings are oriented towards liberation, which involves realising oneself to be Brahman, detached from things.
