Wisdom-Religion The same as Theosophy. The name given to the secret doctrine which underlies every exoteric scripture and religion.
Yoga (Sans.) A school of philosophy founded by Patañjali, but which existed as a distinct teaching and system of life long before that sage. It is Yajñavalkya, a famous and very ancient sage, to whom the White Yajur-Veda, the Satapatha-Brahmana and the Brihak-Aranyaka are attributed and who lived in pre-Mahabharatean times, who is credited with inculcating the necessity and positive duty of religious meditation and retirement into the forests, and who, therefore, is believed to have originated the Yoga doctrine. Professor Max Müller states that it is Yajñavalkya who prepared the world for the preaching of Buddha. Patañjali's Yoga, however, is more definite and precise as a philosophy, and embodies more of the occult sciences than any of the works attributed to Yajñavalkya.
Yogi or Yogin (Sans.) A devotee, one who practices the Yoga system. There are various grades and kinds of Yogis, and the term has now become in India a generic name to designate every kind of ascetic.
Yuga (Sans.) An age of the world of which there are four, which follow each other in a series, namely, Krita (or Satya) Yuga, the golden age; Treta -Yuga, Dvapara-Yuga, and finally Kali-Yuga, the black age-in which we now are.
