This is very nice explanation. Simply by seeing, "Oh, here is a nice, beautiful girl," "Oh, here is a nice, beautiful boy," similarly, "Oh, here is Kṛṣṇa, here is Kṛṣṇa's kathā, here is Kṛṣṇa's topics, oh, here is Kṛṣṇa's temple." Just like, another example is given. Just like the waves of the river. It goes down. We have seen that little river... What is that? Varta? Always going down. In Japan also, I have seen that little river, with sound, going down, going down. So similarly, as the river is going after the sea spontaneously, without any artificial attempt, so such spontaneous love for Kṛṣṇa, or God, that is the perfection of yoga. This is yoga. Yoga means connection. So that connection... In the beginning we may make, revive that connection artificially, but when the connection will be spontaneous, without any check, just like the river water is going down incessantly... Nobody can check it. Ahaituky apratihatā. And why the river is going there? There is no cause. It is going there. Similarly, when our love for Kṛṣṇa will be gliding down like that, without any cause... Without any cause... Generally... The same example again, that spontaneous love does not depend on any cause without. Cause is there. Cause is there, love. There is no other cause. So it is called ahaituky apratihatā. Ahaitukī means without any cause. Just like we generally go to the temple, to the church, with a cause. Just like in Christian church they go. There is cause: "God, give us our daily bread." The cause is bread. "Therefore I have come to church." But when you go to church without any cause, that is real love. "God will give me bread; therefore, let me go to church," this is also nice, but this motivated faith may be lost. If we approach God for some material benefit, for personal sense gratification, that may break at any time. So that is not real love. Real love is without cause. And apratihatā. Apratihatā means which cannot be checked. My love for God cannot be checked by any material condition. Nobody can say that "Because I am poor man, I have to work so hard, I cannot love God now." People say like that. "We shall wait. When I get millions of dollars in my bank balance, then I shall take to Kṛṣṇa consciousness. Now let me earn money." You see? This is not bhakti or attachment. Mayy āsakta. Mayy āsakta manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. Mad-āśrayaḥ means "under My protection." Kṛṣṇa says. So taking shelter of Kṛṣṇa or His representative... Mat means "My man" also. Mad-āśrayaḥ, take shelter of Kṛṣṇa or His representative, and try to practice the yoga by which you will have spontaneous love for Kṛṣṇa.

In that great lake there were different types of lotus flowers. Some of them were bluish, and some of them were red. Some of them grew at night, some in the day and some, like the indīvara lotus flower, in the evening. Combined together, the lotus flowers filled the lake so full that the lake appeared to be a great mine of such flowers. Consequently, on the shores there were swans and cranes, cakravāka, kāraṇḍava and other beautiful water birds standing about.
The word ākaram ("mine") is significant in this verse, for the reservoir of water appeared like a mine from which different types of lotus flowers were produced. Some of the lotus flowers grew during the day, some at night and some in the evening, and accordingly they had different names and different colors. All these flowers were present on that lake, and because the lake was so calm and quiet and filled with lotus flowers, superior birds, like swans, cakravākas and kāraṇḍavas, stood on the shores and vibrated their different songs, making the entire scene attractive and beautiful. As there are different types of human beings, according to the association of the three qualities of material nature, there are similarly different types of birds, bees, trees, etc. Everything is divided according to the three qualities of material nature. Birds like swans and cranes, who enjoy clear waters and lotus flowers, are different from crows, who enjoy filthy places. Similarly, there are persons who are controlled by the modes of ignorance and passion and those who are controlled by the mode of goodness. The creation is so varied that there are always varieties found in every society. Thus on the bank of this lake all the superior birds lived to enjoy that atmosphere created by that great reservoir filled with lotus flowers.
