Step 1: Understanding the statement.
The phrase "Purushavisheshah Ishwarah" means "Ishwara is a special Purusha." It highlights a distinction between ordinary souls (Purushas) and a supreme, eternal, special soul called Ishwara.
Step 2: Connection to Yoga Philosophy.
According to Patanjali’s Yoga Sutra, Ishwara is a unique Purusha, unaffected by afflictions (kleshas), karma, and the cycle of birth and death. Ishwara serves as an object of meditation and a guiding principle for liberation.
Step 3: Elimination of wrong options.
- Sankhya Philosophy: Accepts Purusha and Prakriti but does not accept Ishwara (atheistic).
- Nyaya Philosophy: Believes in God as the creator but not as a "special Purusha" in this sense.
- Vedanta Philosophy: Defines Brahman as the ultimate reality, different from Yoga’s Ishwara concept.
Step 4: Conclusion.
Thus, the theory "Purushavisheshah Ishwarah" belongs to Yoga Philosophy.
