Through sat-sanga, separated souls revive their spiritual brilliance and return to Krishna.Listen — Srila Prabhupada Uvaca
Pradyumna: [chants verse, etc.] [devotees repeat] viṣṇu-śaktiḥ parā proktā kṣetrajñākhyā tathā parā avidyā-karma-samjñānyā tṛtīyā śaktir iṣyate [Cc Madhya 6.154] [break] [00:43] Translation: "Originally, Kṛṣṇa's energy is spiritual, and the energy known as the living entity is also spiritual. However, there is another energy, called illusion, which consists of fruitive activity. That is the Lord's third potency." [break]
Prabhupāda: viṣṇu-śaktiḥ parā proktā kṣetrajñākhyā tathā parā avidyā-karma-samjñānyā tṛtīyā śaktir iṣyate [Cc Madhya 6.154] Viṣṇu-śakti, Bhagavān, the Supreme Absolute Truth, Viṣṇu, all-pervading Personality of Godhead. So His potency... His potency must be also spiritual. Just like the sun globe is reservoir of heat and light.
Everyone will know. So His potency... The sun globe potency, sunshine, is also heat and light. It is not different from the sun. Śakti means potency. Śakti śaktimator abheda.
[The power and the powerful, they are not different-identical.] The potency of a certain person is nondifferent; there is no difference in quality. The same example: the sun and the sunshine. Sunshine is the potency of the sun, but the quality of the sun and the quality of the sunshine is the same—heat and light. So viṣṇu-śakti, there are...
According to the Vedic information, He has got many multifarious potencies. Parāsya śaktir vividhaiva śrūyate [Cc Madhya 13.65, purport]. Different types of śakti. We can see different types of agency, er, what is called, energy is working within this creation.
Take for example the leaves of the tree. Some of them are green; some of them are red; some of them are yellow; some of them are mixed. Similarly fruits—different tastes; flowers—different flavor. Varieties.
But wherefrom it is coming? The sunshine. The sunshine is the same, but it is acting in different way, so we see different manifestation. This is crude material example.
