"So one who is fixed up in Kṛṣṇa, fully surrendered… And one of the points of surrender is that Kṛṣṇa will protect me. Then you are happy. Just like the child. He's fully surrendered to the parents and he is confident that 'My father is there, my mother is there.' So he's happy. Kadāham aikāntika-nitya-kiṅkaraḥ (Stotra-ratna 43). If you know that somebody is there who is my patron, who is my savior, are you not very happy? But if you do everything on your own account, at your responsibility, are you happy? Similarly, if you are convinced in Kṛṣṇa consciousness, that 'Kṛṣṇa will give me protection' and if you are true to Kṛṣṇa, that is the standard of happiness. You cannot be happy otherwise. That is not possible. Eko bahūnāṁ vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13).
That is the fact. Even your, in your rebellious condition Kṛṣṇa is giving you protection. Without Kṛṣṇa's protection you cannot live even for a second. He's so kind. But when you admit it, when you recognize it, then you become happy. Now Kṛṣṇa is giving you protection but you do not know it because you have taken your life at your own risk. Therefore He has given you freedom, 'All right, do whatever you like. As far as possible I will give you protection.' But when you fully surrender, the whole charge is to Kṛṣṇa. That is special. That is special protection. Just like a father. The child who has grown up doesn't care for the father, he's acting freely. What the father can do? 'All right, do whatever you like.' But the child who is fully under the protection of the father, he takes more care.
That is stated in the Bhagavad-gītā you'll find: samo 'haṁ sarva-bhūteṣu (BG 9.29). 'I am equal to everyone.' Na me dveṣyaḥ: 'Nobody is my enemy.' How He can be enemy? Everyone is Kṛṣṇa's son. How he can become enemy to Kṛṣṇa? He is son. That is not possible. He is friend of everyone. But we are not taking advantage of His friendship. That is our disease. That is our disease. He is friend to everyone. Samo 'haṁ sarva-bhūteṣu. But one who is recognizing, he can understand that 'Kṛṣṇa is giving me protection in this way.' This is the way of happiness."
