When Kṛṣṇa was present He was not controlled by anyone. He was only controller. If you study the life of Kṛṣṇa, you will find He is always controller, never controlled by anyone. Therefore the śāstra says, īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ. And about His form? His form is sat-cit-ānanda. How it is? Now, you can distinguish. Your form, this body, is asat; it will not stay. But Kṛṣṇa's form is sat, just the opposite. And your form or my form is full of ignorance, not cit. But Kṛṣṇa's form is full of knowledge, just opposite. And ānanda. My form is so full of miserable condition of life that I have no ānanda, blissfulness. But Kṛṣṇa's form is blissfulness. You will find Kṛṣṇa's picture always smiling and playing on His flute with His cowherd boyfriends or the gopīs or His mother, Yaśodā, always jolly. Ānanda. Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). That is, the Vedānta-sūtra says, "The Absolute Truth by nature is ānandamaya, always jolly."
So if we become in touch with that ānandamaya, that is called self-realization. Brahma-bhūtaḥ prasannātmā (BG 18.54). You get the same qualification. Just like if you touch yourself with fire, you get the quality of fire—you become warm. In any way you come to the fire, you become warm. Similarly, some way or other, you come to Kṛṣṇa. That is called mayy āsakta-manāḥ. Some way or other, you become attached to Kṛṣṇa. This yoga has to be practiced. That is called bhakti-yoga. Yena tena prakāreṇa manaḥ kṛṣṇe niveśayet (Brs 1.2.4). This is the injunction given by the Gosvāmīs. "Somehow or other." Kāmāt krodhāt bhayāt. There are so many ways. One is attached to Kṛṣṇa by lusty desire. Just like the gopīs. The gopīs saw Kṛṣṇa very young boy, very beautiful. Naturally, young girls become attached to beautiful boy. So they became attached.
