Living entities are conscious energy of Krishna, covered by ignorance like clouds obscuring the sun.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Madhya-līlā 6.154–155 [Śrī Kṛṣṇa-niketana] — February 19, 1971, Gorakhpur 710219CC-GORAKPHUR [37:32 Minutes] CcMadhya-06.154–155_710219CC-GORAKPHUR Haṁsadūta: The following lecture was recorded on the evening of February 19th, 1971, at Śrī Kṛṣṇa-niketana, Gorakhpur, Uttar Pradesh.
Prabhupāda: ...tathā parā avidyā-karma-saṁjñānyā tṛtīyā śaktir iṣyate [Cc. Madhya 6.154] So there are three kinds of energies. The Supreme Personality of Godhead has got unlimited energies, just like in the sun there is unlimited energy. You can imagine if so much energy is possible in a material thing which is created by God, or Kṛṣṇa, how much energy Kṛṣṇa has got.
That can be easily... [break] ...partial energy is there in the sun globe. For millions and trillions of years the waves of heat and light emanating from the sun, and still, it is as good as before. Similarly, we can understand from this example that the Supreme Personality has got unlimited energy. The example is given also, just like fire. The same thing... eka-sthāne sthitasyāgner jyotsnā vistāriṇī yathā parasya brahmaṇaḥ śaktis sarvedam akhilaṁ jagat [Viṣṇu Purāṇa 1.22.52] Just like a fire situated in one place distributing unlimitedly, or limitedly, its heats and energies, heats and light, similarly, whatever we are experiencing within our views in this material world, they are simply manifestation of the energy of the Supreme Personality of Godhead. It is also confirmed in the Bhagavad-gītā.
Kṛṣṇa says, mayā tatam idaṁ sarvaṁ jagat avyakta-mūrtinā [Bg. 9.4]: "I am all-pervading, spreading, in this material manifestation, jagat, in impersonal feature, avyakta-mūrtinā." Everything... Avyakta means Kṛṣṇa is not manifested there, but we can feel. Just like when you see some smoke from a distant place, you can immediately understand that there is fire. It is very easy. Similarly, if everything is going on nicely—the sun is rising exactly in the time; the moon is rising exactly in the time; they are illuminating; they are appearing, disappearing; everything is going on, seasonal changes—so if things are going on so nicely, how you can say, "God is dead"? If the management is going on nicely, you cannot say that these things are automatically happening.
No. There is no such thing within your experience which is automatically managed. We must appreciate there is some brain behind it. Professor Einstein, the greatest scientist, he admitted that "As we are advancing in scientific research, we are coming to the conclusion that there is a very big brain behind all this." How you can deny that?
And we are getting direct information from Kṛṣṇa, the Supreme Personality of Godhead, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram hetunānena kaunteya jagad viparivartate [Bg. 9.10] So the progress of the material world... Progress, no. Progress means... In the material objects progress means...
Just like a flower: it is in the bud, then it fructifies. That is progress. Again dwindles and vanishes. Ṣaḍ-vikāra. Just like your body, my body—progress means from babyhood, childhood, boyhood, youthhood.
