This was recommended by Śrīla Parīkṣit Mahārāja, the king. He said that this Kṛṣṇa consciousness is bhavauṣadhi. Bhavauṣadhi means bhava. Bhava means this repeated birth and death. Bhava means you be, and again you not be—not be for few months. Our death means a sleeping for seven months. That is the description we get from the śāstras. Just like you go on sleep every night, so death means to sleep for seven months, unconsciousness, very deep sleep in the womb of the mother. Then as soon as another body is grown up by the ingredients supplied by mother's body or nature, then we get back again consciousness. Just like when we sleep deeply, there is no consciousness. There is consciousness—this is called suṣupti, unconscious. And again, as soon as the body is complete, then we get back our consciousness. Then we become in sleepy condition. Then again, when we come out of the mother's abdomen, that is awakening state. There are three states of conditions: jāgrti, suṣupti and svapna—dreaming condition, awakening condition and unconscious or deep. . . Actually, we do not die. Na jāyate na mriyate vā kadācit (BG 2.20). There is no question of death. It is simply sleeping or deep sleeping, like that.
So if we keep Kṛṣṇa consciousness very active always, that means try to understand Kṛṣṇa from different angles of vision. Here also, as we are studying analytically the functions of agni, but what is this agni? This is also Kṛṣṇa, Kṛṣṇa's energy. Bhūmir āpo anala vāyuḥ (BG 7.4), Kṛṣṇa says in the Bhagavad-gītā. Anala. Anala means agni. Bhinnā me prakṛtir aṣṭadhā. They are not different from Kṛṣṇa. Just like sunshine: sunshine is not different from Kṛṣṇa. Whenever there is sun, wherever there is sun, there is sunshine. Similarly, wherever there is Kṛṣṇa, the Kṛṣṇa's energies are also there. Therefore Viṣṇu. Viṣṇu means all-pervading. So Kṛṣṇa's energies are spread everywhere, just like the illumination, dyotanam. It is called dyotanam, illumination. If the fire is there, there must be illumination. And you have seen in the morning—as soon as the sun. . . before the sun rising actually, before we can see the sun, immediately there is illumination, dyotanam. So the energy, sunshine, is the energy of the sun. It is always there. Sunshine is not differentiated from the sun. Similarly, Kṛṣṇa's energy is not differentiated from Kṛṣṇa. Therefore fire is Kṛṣṇa's energy, air is Kṛṣṇa's energy, water is Kṛṣṇa's energy, land is Kṛṣṇa's energy, the sky is Kṛṣṇa's energy. This is Kṛṣṇa's all-pervasiveness, or God's all-pervasiveness. Parasya brahmaṇaḥ śaktis tathedam akhilaṁ jagat (Viṣṇu Purāṇa): "Akhilam, the entire universe, is expansion of Kṛṣṇa's energy."
