Kṛṣṇa is eternal, and if you fix up your service to Kṛṣṇa, then Kṛṣṇa will accept you as servant. Naturally, you become eternal. There is a very nice story. Nice story not, a fact. Sāvitrī-Satyavān. Sāvitrī-Satyavān. This, I mean to say, incidences are mentioned in the śāstras to give us lesson. Sāvitrī was a very chaste devoted woman. Sāvitrī. In India, to the woman, in order to become very chaste and devoted to husband, they observe the ritualistic ceremony to worship Sāvitrī Satyavān. So Sāvitrī was in love with a boy who was destined to die on the marriage date, but still, she married. She knew that "As soon as I will be married, on the same day, my husband will die." So she pleased the Yamarāja. After the death... The husband died, but she pleased the Yamarāja so much so that Yamarāja was ready to give her some benediction. So Yamarāja said, "What benediction you want?" "Now, as woman, I wish that may be a son of mine, from me." "All right, you will get a son." Then again she said that "If you are taking away my husband, how I will get my son?" So her husband was made alive. So indirectly... So kṛṣṇa-devatāḥ. If you actually want to be eternally blissful, take to kṛṣṇa-devatāḥ. Or there is no need of praying for "Make me immortal." No. If you accept kṛṣṇa-devatāḥ, then automatically... Just like the benediction was that "You... Yes, you will get a son." Automatically her husband was made alive. So kṛṣṇa-devatāḥ.
So Yudhiṣṭhira Mahārāja asking that "Did you see them, the Yadu families, who have Kṛṣṇa as their worshipable Deity?" Dṛṣṭāḥ śrutā vā yadavaḥ. Yadu. Yadavaḥ is plural number. Sva-puryāṁ sukham āsate: "Whether they are happy in their home,"sva-puryām, sva-purī, "Dvārakā?" So in this way Kṛṣṇa consciousness means always thinking of Kṛṣṇa. And make Kṛṣṇa the friend. Kṛṣṇa says that suhṛdaṁ sarva-bhūtānām (BG 5.29). Actually, Kṛṣṇa is the only friend, and He is sitting in everyone's heart. He is so nice friend that He is simply trying to induce us to turn our faith towards Kṛṣṇa. He is coming as avatāra, incarnation. He is giving us advice from within. Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). He's such a nice friend. Although we have left Kṛṣṇa, Kṛṣṇa has not left us. Here He is living with Me within my heart to give me advice, "Please come back." Sarva-dharmān parityajya mām ekam (BG 18.66).
So Kṛṣṇa is so nice friend. He is such a nice friend that even to the enemy He gives the greatest benediction. Just like Pūtanā. Pūtanā came to kill Kṛṣṇa, smearing poison on her breast. But Kṛṣṇa gave her promotion on the motherly platform. Kṛṣṇa is so grateful that "This demon might have come to Me to poison Me, but I have sucked her breast. She has become My mother. Therefore she must get the position of My mother." Kṛṣṇa is so grateful. If you give little service to Kṛṣṇa sincerely, Kṛṣṇa will never forget you. And He's so powerful. If Kṛṣṇa becomes your friend and Kṛṣṇa remembers you, then what you want more? Just imagine. So Kṛṣṇa... Here it is said, kṛṣṇa-devatāḥ. fix up your mind in Kṛṣṇa and be happy.
