Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.28 - Los Angeles, December 6, 1973
So we have got that intimate relation. So when we come to that position to understand our intimate relationship with God, or Kṛṣṇa, that is called svarūpa-siddhi, svarūpa-siddhi. Svarūpa-siddhi means realization of perfection, svarūpa-siddhi. So here Sūta Gosvāmī says sauhārdena gāḍhena, śānta. If an old friend meets another old friend, they become very much delighted. Similarly, if the father meets the lost child, he becomes very delighted and the child also becomes delighted. The husband, wife separated, again they meet. So they become very delighted. It is quite natural. The master and servant after many, many years, if they again meet, they become very delighted. So we have got our relationship with Kṛṣṇa in so many ways, śānta, dāsya, sākhya, vātsalya, mādhurya. Śānta, śānta means neutral, simply to understand the Supreme. Dāsya means a step forward. Just like we say "God is great."
That is śānta, to appreciate the greatness of God. But there is no activity. But when you go step forward, that "God is great, so I am serving so many society, friendship, loves, cats, dogs and so many I'm loving. Why not let me love the greatest?" that is called dāsya. Simply to realize God is great that is also very good. But when you voluntarily go forward, "Now why not serve the great?" Just like from ordinary service, those who are engaged in service, they want to try to change from the inferior service to the superior service. Service is there. But superior service is somebody gets government service. He thinks it is very nice. So similarly, as we serve, when we desire to serve the great, that will give us peaceful life. That is śānta, dāsya.
