Âdi, or Âdhi Budha, the One, or the First, and Supreme Wisdom, is a term used by Âryâsanga in his secret treatises, and now by all the mystic Northern Buddhists. It is a Sanskrit term, and an appellation given by the earliest Âryans to the Unknown Deity; the word “Brahmâ” not being found in the _Vedas_ and the early works. It means the Absolute Wisdom, and Âdibhûta is translated by Fitzedward Hall, “the primeval uncreated cause of all.” Æons of untold duration must have elapsed, before the epithet of Buddha was so humanized, so to speak, as to allow of the term being applied to mortals, and finally appropriated to one whose unparalleled virtues and knowledge caused him to receive the title of the “Buddha of Wisdom Unmoved.” _Bodha_ means the innate possession of divine intellect or understanding; _Buddha_, the acquirement of it by personal efforts and merit; while _Buddhi_ is the faculty of cognizing, the channel through which divine knowledge reaches the Ego, the discernment of good and evil, also divine conscience, and the Spiritual Soul, which is the vehicle of Âtmâ. “When Buddhi absorbs our Ego‐tism (destroys it) with all its Vikâras, Avalokiteshvara becomes manifested to us, and Nirvâna, or Mukti, is reached,” Mukti being the same as Nirvana, _i.e._, freedom from the trammels of Mâyâ or Illusion. _Bodhi_ is likewise the name of a particular state of trance‐condition, called Samâdhi, during which the subject reaches the culmination of spiritual knowledge. Unwise are those who, in their blind and, in our age, untimely hatred of Buddhism, and, by reäction, of Budhism, deny its esoteric teachings, which are those also of the Brâhmans, simply because the name suggests what to them, as Monotheists, are noxious doctrines. _Unwise_ is the correct term to use in their case. For in this age of crass and illogical materialism, the Esoteric Philosophy alone is calculated to withstand the repeated attacks on all and everything man holds most dear and sacred in his inner spiritual life. The true philosopher, the student of Esoteric Wisdom, entirely loses sight of personalities, dogmatic beliefs and special religions. Moreover, Esoteric Philosophy reconciles all religions, strips every one of its outward human garments, and shows the root of each to be identical with that of every other great religion. It proves the necessity of a Divine Absolute Principle in Nature. It denies Deity no more than it does the sun. Esoteric Philosophy has never rejected God in Nature, nor Deity as the absolute and abstract _Ens_. It only refuses to accept any of the gods of the so‐called monotheistic religions, gods created by man in his own image and likeness, a blasphemous and sorry caricature of the Ever‐Unknowable. Furthermore, the records we mean to place before the reader embrace the esoteric tenets of the whole world since the beginning of our humanity, and Buddhistic Occultism occupies therein only its legitimate place, and no more.
