Real yoga is buddhi-yoga, the yoga of devotional service, which brings about direct perception of the Supreme Lord. When the devotee meets the Lord face to face, liberation takes the form of a woman and is at his beck and call, eager to serve him, and she is accompanied by personified material opulence, sense pleasure, and religiosity, all of whom wait upon the devotee like servants. The pure devotees of the Lord are all embodiments of perfection in yoga; thus the four Vedic goals are truly at their beck and call. And beyond these four goals is the supreme destination: superconsciousness, or God consciousness. This is the fifth and paramount Vedic goal. One who has reached the state of unalloyed Kṛṣṇa consciousness is an extremely rare personality—one in a million devotees, according Lord Caitanya.
Such an elevated state of consciousness is the last word in yoga. None of the other yoga processes, such as haṭha-yoga or rāja-yoga, can bring one to this platform. Buddhi-yoga lies far above these yoga practices, which are mostly physical disciplines. Buddhi-yoga, however, is a spiritual discipline for self-realization. This realization is a full perception of the nondual Absolute Truth, whereby one sees everything resting in the Supreme Lord and the Supreme Lord in everything.
