When we think of Yoga, we used to think of some old bearded yogi standing on his head, or more recently of young beautiful men & women in athletic clothing posing serenely, or a class full of people stretching on yoga mats. But actually the meaning of yoga is far beyond any of the physical gymnastics we tend to associate with the word. There are many systems of yoga, namely; karma yoga, jnana yoga, dhayana yoga, hatha yoga, bhakti yoga, and so many patterns of yoga. But as we understand from the Bhagavad-gita:
…in the Bhagavad-gītā it is clearly stated that…yoga means to get into touch with the Supreme Lord. The process, however, includes several bodily features such as āsana, dhyāna, prāṇāyāma and meditation (from purport SB 1.2.28-29)
…The word yoga means “link.” Any system of yoga is an attempt to reconnect our broken relationship with the Supreme Personality of Godhead. There are different types of yoga, of which bhakti-yoga is the best. In other yoga systems, one must undergo various processes before attaining perfection, but bhakti-yoga is direct. (from purport SB 10.2.6)
…The culmination of all kinds of yoga practices lies in bhakti-yoga. All other yogas are but means to come to the point of bhakti in bhakti-yoga. Yoga actually means bhakti-yoga; all other yogas are progressions toward the destination of bhakti-yoga. From the beginning of karma-yoga to the end of bhakti-yoga is a long way to self-realization. Karma-yoga, without fruitive results, is the beginning of this path. When karma-yoga increases in knowledge and renunciation, the stage is called jñāna-yoga. When jñāna-yoga increases in meditation on the Supersoul by different physical processes, and the mind is on Him, it is called aṣṭāṅga-yoga. And, when one surpasses the aṣṭāṅga-yoga and comes to the point of the Supreme Personality of Godhead Kṛṣṇa, it is called bhakti-yoga, the culmination. Factually, bhakti-yoga is the ultimate goal, but to analyze bhakti-yoga minutely one has to understand these other yogas. The yogī who is progressive is therefore on the true path of eternal good fortune. One who sticks to a particular point and does not make further progress is called by that particular name: karma-yogī, jñāna-yogī or dhyāna-yogī, rāja-yogī, haṭha-yogī, etc. If one is fortunate enough to come to the point of bhakti-yoga, it is to be understood that he has surpassed all the other yogas. Therefore, to become Kṛṣṇa conscious is the highest stage of yoga, just as, when we speak of Himalayan, we refer to the world’s highest mountains, of which the highest peak, Mount Everest, is considered to be the culmination.
It is by great fortune that one comes to Kṛṣṇa consciousness on the path of bhakti-yoga to become well situated according to the Vedic direction. The ideal yogī concentrates his attention on Kṛṣṇa, who is called Śyāmasundara, who is as beautifully colored as a cloud, whose lotus-like face is as effulgent as the sun, whose dress is brilliant with jewels and whose body is flower garlanded. Illuminating all sides is His gorgeous luster, which is called the brahmajyoti. He incarnates in different forms such as Rāma, Nṛsiṁha, Varāha and Kṛṣṇa, the Supreme Personality of Godhead, and He descends like a human being, as the son of Mother Yaśodā, and He is known as Kṛṣṇa, Govinda and Vāsudeva. He is the perfect child, husband, friend and master, and He is full with all opulences and transcendental qualities. If one remains fully conscious of these features of the Lord, he is called the highest yogī. (Bhagavad-gita 6.47)
The very word yoga means connecting link with the supreme being. We accept Krishna as the supreme being, and nobody is equal to him or greater than him. (Letter to Sri Krishna C. Batra – Vrindaban 8 December, 1975)
