The Bhagavad Gita presents us with a unitary system of Yoga, one clear and systematic path, wherein all four Yoga techniques of jnana, karma, bhakti and classical ashtanga are - together – all considered crucial for spiritual realization. These four supposedly different paths, in actuality, represent four aspects of one, unified, integral Yoga system. They are akin to the four sides of a square. If one of the sides of the square is missing, then the very structural integrity and being of the square is itself compromised. Indeed, it no longer is logically qualified as a "square" at all. Similarly, the complete
and authentic path of Yoga spirituality must include all these four components of Yoga in order to be fully appreciated.
It is true that these four Yogas are linked by their common emphasis on devotional meditation upon, and the ultimate loving absorption of our awareness in, the Absolute. However, it is also inarguably clear that Krishna considers bhakti-yoga, or the discipline of focused devotional consciousness, to be not merely one component of these four branches of Yoga, but as the very essence and goal of all Yoga practice itself. Unlike the other aspects of the Yoga path, bhakti (devotional meditation) is distinguished by the fact that it is not only a means (upaya) for knowing God, but it is simultaneously also the goal (artha) of all human existence. As the means, bhakti designates devotional meditation; as the goal, bhakti means devotional consciousness. At no time does one abandon the practice of bhakti, even upon achieving liberation. Rather, devotional consciousness focused with one-pointed awareness upon the Absolute represents the very goal of the entire Yoga system.
