Kṛṣṇa is within your heart. It is not that you have to create a Kṛṣṇa or God or you have to call. He is there. But due to darkness we cannot see Him. But by chanting this Hare Kṛṣṇa mantra, ceto-darpaṇa-mārjanam (CC Antya 20.12), by cleanings the core of our heart, you will be able to see Kṛṣṇa within yourself. Yena mām upayānti te. The instruction is how he can come back, go back to home, back to Godhead—mokṣyase aśubhāt—being free from all inauspicity. That stage can be attained. How? Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10). If you engage yourself always in His service. Satata-yuktānām. Satata means always, always engaged in His service. Bhajatāṁ prīti-pūrvakam. And worshiping the Lord with prīti, love, prīti... Bhajatāṁ prīti-pūrvakam. So this is being instructed to the students who have entered this institute, how to worship the Deity. The Deity worship is there just to give chance to the devotee satatam, satata-yuktānām—always engaged in Kṛṣṇa's service. From early morning, half past three, four, up to night, ten, they are engaged. That is called satata-yuktānām. Only a few hours given to them for taking rest because, after all, we have got this material body. It requires little rest. Otherwise there is no question of resting. Twenty-four hours engaged in the service of Kṛṣṇa.
So that is possible as you become advanced. Just like the six Gosvāmīs. They attained that stage. They were not sleeping at night. Giving service. It is said, nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau lokānāṁ hita-kāriṇau. Nidrāhāra-vijitau. This is spiritual life. The more you conquer over the necessities of this body. Our necessities, the created necessities, they are necessities of the body. The body requires to eat. The body requires rest. The body requires sex. The body requires defense. But the soul does not require. So more you become advanced in spiritual consciousness, the material necessities become minimum. Nidrāhāra-vihārakādi-vijitau **. That is possible. That is not story. There are many instances, and the more you become advanced in Kṛṣṇa consciousness, spiritual life, these necessities of life, necessities of body... Because body is different from the spirit soul. The necessities of the body is material, and the necessities of the soul is spiritual. But unfortunately, although the spirit is there, we are so much absorbed in material consciousness, we do not understand what is spirit soul. We are simply busy in taking care of the body. So this is not very good condition. This is material condition. And it is very risky if we simply... Simply to take care of the body means creating different desires. "I shall be happy in this way. I shall be happy in this way." So nature's mercy is that as soon as you think that you will enjoy life like this, she will give you good opportunity. That means changing a body wherein you can enjoy the material facilities very easily.
I have several times given example. There are different types of bodies: animals, birds, beasts, demigods, human being, many varieties of life, 8,400,000, higher life, lower life. So those who are associating with the base qualities of material nature, they get lower life. That is natural. Just like you contaminate a kind of disease. It will become manifest in due course of time. So this is going on. But if we understand this knowledge as Kṛṣṇa is speaking, rāja-vidyā rāja-guhyaṁ pavitram idam uttamam, then pratyakṣāvagamaṁ dharmyam. Dharma. One meaning of dharma is the basic principle of our life or the occupational duty of our life, dharma. Occupational duty of our life, that is called dharma. Generally in the English dharma is translated by the word religion, a kind of faith. But actually dharma means the characteristic. That is real meaning of dharma, characteristic.
