As soon as the electricity will fail, then whole city will be in darkness.
So the nature of this . . . and the Vedic mantra also says that "Don't remain in this darkness." Tamaso mā jyotir gamaya (Bṛhad-āraṇyaka Upaniṣad 1.3.28): "Just try to transfer yourself in that illuminated world." Jyotir gamaya. Jyoti means illumination. So this world, this material world, is full of darkness. Darkness, one meaning of darkness is ignorance. And another darkness, you know, without . . . absence of light. So this nature of this material world is darkness. So if we understand the Kṛṣṇa science and the activities of Kṛṣṇa: how He comes, how He works, what is the mission of His activity . . .
Because as the Supreme Lord, He has nothing to do. But why He comes? In the Vedic literature you'll find, na tasya kāryaṁ karaṇaṁ ca vidyate (Śvetāśvatara Upaniṣad 6.8).
The description of the Supreme Brahman is described there, that, upaniṣad . . . na tasya kāryaṁ karaṇaṁ ca vidyate: "The Supreme, the Absolute, He has nothing to do." He has nothing to do. Just like if we want to do, have something, we have to do. But there, the Absolute, He has nothing to do. Na tasya kāryaṁ karaṇaṁ ca vidyate.
Na tat-samaś cābhyadhikaś ca dṛśyate (Śvetāśvatara Upaniṣad 6.8). And there is nobody who is equal to Him and nobody who is above Him. That means everyone is below Him. Nobody equal to Him and nobody above Him; that means everybody is below. Na tasya kāryaṁ karaṇaṁ ca vidyate na tat-samaś cābhyadhikaś ca dṛśyate, parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8): "The Supreme has got many, manifold energies." Therefore everything is done, svābhāvikī jñāna-bala-kriyā ca.
And His knowledge and His activities are svābhāvikī, natural. Natural. Just like we have to acquire knowledge from a greater personality, but He has got all the natural, all knowledge. Just like Kṛṣṇa is speaking this Bhagavad-gītā to Arjuna, but He was never taught of Bhagavad-gītā. I am speaking to you Bhagavad-gītā, just learning from my spiritual master. So I have to learn it. But when Kṛṣṇa spoke, He hadn't . . . had not to learn it. He had no business to learn it. Because svābhāvikī jñāna-bala-kriyā ca: His knowledge is natural.
So these things are to be understand. That one who understands the science of Kṛṣṇa in truth, then the benefit is, the result is that he, he no more comes back to this world of darkness. Tyaktvā dehaṁ punar janma naiti (BG 4.9). Neither he has to undergo the repeated birth and death. We are just now undergoing the term of repeated birth and death under different species of life. So that thing will be stopped.
So human, human mission, human life should be utilized for this purpose. This is the dharma. This is real our engagement. We have diverted our engagement for satisfying our material needs. Oh, that is not the mission of human being. That is the mission of lower animals.
