"Pure devotional service is the only means to attract Kṛṣṇa." You cannot attract Kṛṣṇa. Kṛṣṇa is the Supreme Personality of Godhead, with full opulences. So you cannot attract Kṛṣṇa by your richness, by your reputation, by your education, by your beauty or by your strength or renunciation. No. You cannot attract Kṛṣṇa by all these things, because He's already full. You cannot attract by anything, any opulence, Kṛṣṇa, because He's ātmārāma. But if you offer something to Kṛṣṇa, it is for your benefit.
The example is given, just like the original person is decorated, in the mirror the reflection of the person is also decorated. Similarly, if you decorate the Deity gorgeously, you will feel happy. Kṛṣṇa has many devotees, or many things for being decorated. But if you, in the temple, if you offer Kṛṣṇa all nice things, all nice flowers, all nice dress, all nice food, everything all nice, then you will feel happy. That is your interest.
Therefore pure devotional service is the only means to attract Kṛṣṇa. Attract Kṛṣṇa . . . Kṛṣṇa will be happy in this way, that you are doing so much for Kṛṣṇa. Kṛṣṇa has everything, but your devotional service, that sincerity of purpose, will attract. My Guru Mahārāja used to say that "Do not try to see Kṛṣṇa. Render your service in such a nice way that let Kṛṣṇa see you." When Kṛṣṇa sees you, then your mission is perfect.
We cannot see . . . ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). We cannot perceive Kṛṣṇa by our senses, but when our senses are engaged in satisfying Kṛṣṇa, then Kṛṣṇa sees us. Svayam eva sphuraty adhaḥ (Brs. 1.2.234). And when Kṛṣṇa sees us, then our life is successful. And how Kṛṣṇa can see us? Simply by our devotional service. Otherwise, you cannot satisfy Kṛṣṇa by opulence, by education, by scholarship, by beauty, by riches. No. These things Kṛṣṇa has all perfectly. He's full with all these opulences. Bhaktyā mām abhijānāti (BG 18.55). If you want to attract Kṛṣṇa, then be engaged in pure devotional service.
