Sāṃkhya Philosophy: Understanding the 25 Elements

The Sāṃkhya school of Indian philosophy posits a system of $25$ fundamental principles or elements, known as tattvas. These tattvas represent the constituents of the universe and consciousness.

Reasoning for Correct Answer

The $25$ Sāṃkhya tattvas are typically categorized as follows:

• Prakṛti (Primordial Matter): The unmanifest source.
• Mahat (Cosmic Intellect / Buddhi): The first evolute.
• Ahaṃkāra (Ego): The principle of individuation, evolving from Mahat.
• Eleven Indriyas (Instruments): Evolving from Ahaṃkāra.
  • Manas (Mind): The sensory-motor integrating faculty.
  • Five Jñānendriyas (Cognitive Faculties): Sight, sound, smell, taste, touch.
  • Five Karmendriyas (Active Faculties): Speech, grasping, locomotion, excretion, procreation.
• Five Tanmātrās (Subtle Elements): Sound, touch, form, taste, smell; evolving from Ahaṃkāra (specifically the sattvic aspect).
• Five Mahābhūtas (Gross Elements): Ether, air, fire, water, earth; evolving from the Tanmātrās (specifically the tamasic aspect).
• Puruṣa (Consciousness/Spirit): Pure consciousness, distinct from Prakṛti and its evolutes.

Now, let's evaluate the given options:

• A. Manas: Included as one of the $11$ Indriyas within the $25$ tattvas.
• B. Buddhi: Included as Mahat, the first evolute of Prakṛti.
• C. Ahaṃkāra: Included as the second evolute of Prakṛti.
• D. Pañca tanmātrā: Included as the five subtle elements.
• E. Sapta Padārtha: This term refers to categories in other philosophical systems (like Nyāya) and is not part of the standard Sāṃkhya list of $25$ tattvas.

Therefore, Manas, Buddhi, Ahaṃkāra, and Pañca tanmātrā are all part of the $25$ Sāṃkhya elements.

Conclusion

Based on the analysis, options A, B, C, and D are correctly included in the $25$ elements of Sāṃkhya philosophy. Option E is not.
