The ancient rishi Patanjali defines “yoga” as “control of the fluctuations of the mind-stuff.” {FN24-4} His very short and masterly expositions, the YOGA SUTRAS, form one of the six systems of Hindu philosophy. {FN24-5} In contradistinction to Western philosophies, all six Hindu systems embody not only theoretical but practical teachings. In addition to every conceivable ontological inquiry, the six systems formulate six definite disciplines aimed at the permanent removal of suffering and the attainment of timeless bliss. The common thread linking all six systems is the declaration that no true freedom for man is possible without knowledge of the ultimate Reality. The later UPANISHADS uphold the YOGA SUTRAS, among the six systems, as containing the most efficacious methods for achieving direct perception of truth. Through the practical techniques of yoga, man leaves behind forever the barren realms of speculation and cognizes in experience the veritable Essence. The YOGA system as outlined by Patanjali is known as the Eightfold Path. The first steps, (1) YAMA and (2) NIYAMA, require observance of ten negative and positive moralities-avoidance of injury to others, of untruthfulness, of stealing, of incontinence, of gift-receiving (which brings obligations); and purity of body and mind, contentment, self-discipline, study, and devotion to God. The next steps are (3) ASANA (right posture); the spinal column must be held straight, and the body firm in a comfortable position for meditation; (4) PRANAYAMA (control of PRANA, subtle life currents); and (5) PRATYAHARA (withdrawal of the senses from external objects). The last steps are forms of yoga proper: (6) DHARANA (concentration); holding the mind to one thought; (7) DHYANA (meditation), and (8) SAMADHI (superconscious perception). This is the Eightfold Path of Yoga {FN24-6} which leads one to the final goal of KAIVALYA (Absoluteness), a term which might be more comprehensibly put as “realization of the Truth beyond all intellectual apprehension.” “Which is greater,” one may ask, “a swami or a yogi?” If and when final oneness with God is achieved, the distinctions of the various paths disappear. The BHAGAVAD GITA, however, points out that the methods of yoga are all-embracive. Its techniques are not meant only for certain types and temperaments, such as those few who incline toward the monastic life; yoga requires no formal allegiance. Because the yogic science satisfies a universal need, it has a natural universal applicability. A true yogi may remain dutifully in the world; there he is like butter on water, and not like the easily-diluted milk of unchurned and undisciplined humanity. To fulfill one’s earthly responsibilities is indeed the higher path, provided the yogi, maintaining a mental uninvolvement with egotistical desires, plays his part as a willing instrument of God.
