You will find the picture of Kṛṣṇa. Here is Kṛṣṇa's picture, and there are many other pictures also. Here is also. He's attractive to the animals, He's attractive to the trees, He's attractive to the flowers, He's attractive to the water, and what to speak of human being. He's attractive; therefore His name is Kṛṣṇa. Kṛṣṇa means all-attractive. So if any suitable name can be assigned to the Supreme Personality of Godhead, it is Kṛṣṇa. That is the verdict of the Vedic literature. Now Kṛṣṇa says: "If you develop your attachment for Me," mayy āsakta-manaḥ pārtha, "My dear Arjuna . . ." Mayy āsakta-manaḥ pārtha yogaṁ yuñjan mad-āśrayaḥ (BG 7.1). It is a yoga, yoga system.
You have heard the name of yoga system. There are different kinds of yoga systems, but the foremost and the topmost yoga system is to develop your attachment or constantly being in touch with the Supreme Personality of Godhead. That is first-class yoga. yoga actually means to make your connection with the Supreme Lord. That is yoga. yoga means "addition," "connect." And viyoga . . . the opposite word is viyoga. Just like addition and subtraction. Similarly, the yoga, and the opposite word is viyoga, or viyoga. Viyoga means when we are detached from God, and yoga means when we are attached to God. This is the two different words. So here it is recommended, yogaṁ yuñjan mad-āśrayaḥ. It is another practice of yoga, the topmost yoga.
