In the Bhagavad-gītā it is said āsuri. Āsuri, this word has come from this āsura. Adjective. Asura is nominative. So from āsura, it becomes āsuri. Āsuri-bhāvam āśritāḥ. Those who are atheists, they do not surrender. They do not like the idea of God or Kṛṣṇa consciousness. But they do not know what is God or what is the ultimate end, who is the original cause. They do not know. Even the theists, they also do not know. They know Kṛṣṇa, but it is impossible to understand what is the limit of Kṛṣṇa's energies, just like we were discussing this morning.
So unlimited. Unlimited. Yasyāntaṁ na viduḥ surāsura-gaṇa devāya tasmai namaḥ. Devāya, that Supreme Lord, we simply offer our respectful obeisance. It is not possible to know perfectly what is the potency and energy of God. The atheists, they do not know at all. But theists, devotees, they know, but that is not complete. Even Kṛṣṇa does not know how much powerful He is. That is called unlimited.
So surāsura-gaṇa udadhiṁ mathnatām. Churning. Once upon a time they churned the whole ocean. Now, churning the ocean . . . you have got experience, churning the milk in a pot or something else in a pot. But the pot is the ocean, the Pacific Ocean, and the rod is Mandarācala Hill. And one side, the asuras, and the other side, the suras. So the churning rod must be placed on something, a pivot.
That is kamaṭha-rūpeṇa. Lord accepted the . . . because the kamaṭha, the tortoise, can live within the water and without the water also. They can live on the land and within the water. So the churning rod, Mandarācala Hill, was placed on the shell, on the back of the . . . keśava dhṛta-kūrma-śarīra. Kṣitir iha vipulatare tiṣṭhati tava pṛṣṭhe. This pṛṣṭha, he is carrying.
