Bodhisattva (Sanskrit) [from bodhi wisdom + sattva essence] He whose essence has become intelligence; exoterically, one who in one or a few more incarnations will become a buddha. Occultly, when
"a human being, has reached the state where his ego becomes conscious, fully so, of its inner divinity, becomes clothed with the buddhic ray; where, so to say, the personal man has put on the garments of inner immortality in actuality, on this earth, here and now -- that man is a Bodhisattva. His higher principles have nearly reached Nirvana. When they do so finally, such a man is a Buddha, a human Buddha, a Manushya-Buddha. Obviously, if such a Bodhisattva were to reincarnate, in the next incarnation or in a very few future incarnations thereafter, he would be a Manushya-Buddha. A Buddha, in the esoteric teaching, is one whose higher principles can learn nothing more. They have reached Nirvana and remain there; but the spiritually awakened personal man, the Bodhisattva, the person made semi-divine to use popular language, instead of choosing his reward in the Nirvana of a less degree, remains on earth out of pity and compassion for inferior beings, and becomes what is called a Nirmanakaya . . . a Bodhisattva is the representative on earth of a Dhyani-Buddha or Celestial Buddha -- in other words one who has become an incarnation or expression of his own Divine Monad" (OG 19).
The dhyani-buddhas who each watch over one of the rounds and the great root-races on the different globes of our planetary chain, are said to send their bodhisattvas, their spiritual or human correspondents, during every round and race.
"These Dhyani Buddhas emanate, or create from themselves, by virtue of Dhyana, celestial Selves -- the super-human Bodhisattvas. These incarnating at the beginning of every human cycle on earth as mortal men, become occasionally, owing to their personal merit, Bodhisattvas among the Sons of Humanity, after which they may re-appear as Manushi (human) Buddhas" (SD 1:571).
"The exoteric teaching which says that every Dhyani-Buddha has the faculty of creating from himself, an equally celestial son -- a Dhyani-Bodhisattva -- who, after the decease of the Manushi (human) Buddha, has to carry out the work of the latter, rests on the fact that owing to the highest initiation performed by one overshadowed by the 'Spirit of Buddha' . . . a candidate becomes virtually a Bodhisattva, created such by the High Initiator" (SD 1:109).
