So Caitanya Mahāprabhu... That is the ācārya process. Ācārya. Acinoti śāstra, śāstrārtha. One who knows the śāstra-artha, one who has assimilated the śāstrārtha, he is ācārya. So immediately He is giving evidence from śāstra.
- viṣṇu-śaktiḥ parā proktā
- kṣetrajñākhyā tathā parā
- avidyā-karma-saṁjñānyā
- tṛtīyā śaktir iṣyate
- (CC Madhya 6.154)
The... He has divided the whole energy of Kṛṣṇa into three: cit-śakti, jīva-śakti, and māyā-śakti. So the evidence is quoted from śāstra, Viṣṇu-Purāṇa, that viṣṇu-śaktiḥ parā proktā. Originally the Kṛṣṇa's energy is cit-śakti. Cit-śakti means spiritual energy, originally. Everything... Just like the sun and the sunshine. The sunshine originally shining, but when it is covered by cloud it is not shining. Within the cloud the real sunshine is there. So this material energy means it is covered by ignorance. This is the difference between spiritual energy and material energy. There is no two energies. Energy is one: viṣṇu-śakti parā proktā. That is parā, spiritual energy. Kṣetrajñākhyā tathā parā. Kṣetrajñākhyā tathā parā. Kṣetrajña means jīva-śakti, one who knows kṣetra and kṣetrajña. This subject matter is there in the Thirteenth Chapter of Bhagavad-gītā. Kṣetra-kṣetrajñayor jñānam. So when Arjuna inquired, kṣetra-jñam, Kṛṣṇa replied, idaṁ śarīraṁ kṣetram abhidhīyate: "This body is kṣetra, and one who knows this body..." Just like I say, "It is my body," so I am kṣetrajña.
