Anuśīlanam, culture of Kṛṣṇa favorably, that Kṛṣṇa, how Kṛṣṇa is pleased, we should do like that. We should know how Kṛṣṇa is pleased. How you can know? The Bhagavad-gītā is there, and take the right interpretation from a right person. Then you'll know what Kṛṣṇa wants and do accordingly. Ānukūlyena kṛṣṇānuśīlanaṁ bhaktir uttamā. Then you are elevated to the first-class devotional service. You see? First-class devotional service. Everything should be anukūla. Anukūla means favorable.
So these things are there. It is a great science, and we have got immense literature for this. If we have got time, we can utilize. We can understand this science and prepare ourself for the supreme benefit.
So puruṣa . . . so in that spiritual planet, puruṣaḥ sa paraḥ pārtha, there is the Supreme Personality of Godhead. In the spiritual planet there are . . . just like you see here millions of planets or stars within this universe. This universe is a small particle only. There are many universes like this. And in the spiritual sky there are three . . . this is only one-fourth manifestation of the planets. There are . . . other three-fourth is there in the spiritual sky. That information is there in the Bhagavad-gītā. Ekāṁśena sthito jagat (BG 10.42).
So each and every spiritual planet, there is expansion of Kṛṣṇa, and they are differently named. In that picture we will find, our Bhāgavata. Innumerable. So puruṣa. They are all puruṣa. Puruṣa means the person. They are not imperson. Puruṣa. Puruṣaḥ sa paraḥ. But superior. Puruṣaḥ sa paraḥ pārtha bhaktyā labhyaḥ. You can approach that puruṣa simply by devotional service, not by challenge, not by philosophical speculation or not by exercise of this yoga and that yoga. No. Simply by surrender and devotional service. It is clearly stated.
