Jñānendriyas — The Five Organs of Sensory Knowledge
Jñānendriyas (Sanskrit: jñāna = knowledge + indriya = sense organ; 'sense organs of knowledge') are the five organs through which the jīvātmā receives information about the external world — the instruments of perception.
The Five Jñānendriyas:
- Śrotra (ears) — perceives śabda (sound), operates through ākāśa (space)
- Tvak (skin) — perceives sparśa (touch), operates through vāyu (air)
- Cakṣu (eyes) — perceives rūpa (form/sight), operates through agni (fire)
- Jihvā (tongue) — perceives rasa (taste), operates through āpas (water)
- Ghrāṇa (nose) — perceives gandha (smell), operates through pṛthivī (earth)
Relationship to Tanmātrās and Mahābhūtas: Each jñānendriya arises from a combination of its corresponding tanmātrā and mahābhūta. The ear arises from the śabda tanmātrā and ākāśa; the skin from sparśa and vāyu; etc.
In Sādhana: The jñānendriyas, when turned toward Bhagavān — hearing His names, seeing His forms, touching His feet — become instruments of liberation. When turned toward material sense-objects, they bind. 'The same ears that are enslaved to music can be liberated by Divya Prabandham.'
