So there are many devotees, ananta devotees, only not one or two. So Kṛṣṇa has to satisfy every one of them. That is not difficult for Him. Ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (BG 4.11). There are so many millions and trillions of devotees. They are surrendering to Kṛṣṇa and desiring to serve Him in his different propensity, and Kṛṣṇa fulfills everyone's desire.
So to understand Kṛṣṇa, kṛṣṇa-upadeśa, to know about Kṛṣṇa, that is Kṛṣṇa consciousness movement. Caitanya Mahāprabhu's mission is like that. Yāre dekha, tāre kaha 'kṛṣṇa'-upadeśa (CC Madhya 7.128). If you study just like here, analytical study of fire... Dyotanam, illumination; pacanam, digesting; pānam, increasing thirst. If you don't feel thirsty, that means the agni, or the fire element within the stomach, is not working. Agni-māndya. Māndya, the word comes from manda. Manda means slow. So the Ayurvedic treatment, they say it, agni-māndya. So when there is agni-māndya, there is medicine how to ignite the fire again. There is fire within the stomach, within the abdomen. Everything is there. So according to Ayurveda treatment, this kapha, pitta, vāyu. Vāyu... About the air we have discussed something in the previous verses. Now agni and then kapha, mucus. Mucus, bile, and fire.
