Īśvara, the Supreme Personality of Godhead, is staying within the heart of everyone. So within the heart from everyone if He can come out, oh what is the difficulty for Him, from the . . . within the womb of somebody He comes out? Where is the difference between heart and womb? And Kṛṣṇa entered within the womb of Mahārāja Parīkṣit's mother to save Mahārāja Parīkṣit. So Kṛṣṇa can do anything. Therefore Kuntī said that antar bahiḥ: "Kṛṣṇa is within and without. Still, we cannot see." Kṛṣṇa is within and without, both ways, but we cannot see either within or without. This is called māyā. This is called māyā.
So this is the problem. But that is not the problem for Kṛṣṇa. But that is problem for us. Because we are very minute spark of Kṛṣṇa, as the spark has the chance of being extinguished out of the fire, similarly, being separated from Kṛṣṇa, being entangled in this material energy, we have forgotten. Our spiritual quality, burning quality, just like fire, that is now extinguished. It is not exactly extinguished; almost extinguished. We have forgotten. But it can be again brought into the original position by fanning. Just like there is small fire in the charcoal. You fan it, and it will gradually become a big fire. So this Kṛṣṇa consciousness movement is fanning that spiritual spark to come into full consciousness. Go on fanning like that. That is the rules and regulation—attending this class, hearing this Śrīmad-Bhāgavatam, Bhagavad-gītā. Twenty-four hours be engaged. That is real business. Dhyāyan, always, constantly, hṛdi brahma paraṁ dhyāyan. Dhyāyan means medi . . . this is meditation. And who is Para-brahman? Kṛṣṇa. Paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12).
So this is the process. You simply think of Kṛṣṇa twenty-four hours, dhyāyan. That is the process. We are engaged in the Deity worship of Kṛṣṇa. We are engaged in chanting Kṛṣṇa's name. We are engaged in Kṛṣṇa's business or Kṛṣṇa's propaganda. In this way, if you simply think of Kṛṣṇa twenty-four . . . if you, I mean to say, made your life . . . make your life with that spirit, Kṛṣṇa . . . this is Kṛṣṇa consciousness, twenty-four hours, satataṁ smartavyo viṣṇuḥ, the process is only thinking of Kṛṣṇa in different engagements. The process, real process, is to think of Kṛṣṇa. Then hṛdi, "Within the heart," hṛdi brahma paraṁ dhyāyan nāvarteta yato gataḥ, then you will be transferred to the Kṛṣṇaloka, because you are thinking of Kṛṣṇa always. So tyaktvā dehaṁ punar janma naiti (BG 4.9): after giving up this body, you will not have any more material body. Yad gatvā na nivartante (BG 15.6). You will reach immediately. Tyaktvā dehaṁ punaḥ, mām eti, immediately.
The . . . as there are different forces, material forces, then subtler than the matter, mind, mind's force, similarly, there is spiritual force. Mind force, you know. You are sitting here; immediately, within a second, you can go thousands of miles away. Immediately. That is mind's force. And the spiritual force is still more greater than the mind's force. So tyaktvā deham, as soon as you give up this body, immediately, within the second, you reach Kṛṣṇaloka. That is perfection.
