Leaving the early Buddha legends and the solid ground of history, the makers of the newer Buddhist doctrines in Nepal occupied themselves with developing the theory of Buddhahood and of the Buddhas;[16] for we must ever remember that Buddha[17] is not a proper name, but a common adjective meaning enlightened, from the root to know, perceive, etc. They made constant and marvellous additions to the primitive doctrine, giving it a momentum which gathered force as the centuries went on; and, as propaganda, it moved against the sun. This development theory ran along the line of _personification_. Not being satisfied with "the wheel of the law," it personified both the hub and the spokes. It began with the spirit of kindness out of which all human virtues rise, and by the power of which the Buddhist organization will conquer all sin and unbelief and become victorious throughout the world. This personification is called the Maitreya Buddha, the unconquerable one, or the future Buddha of benevolence, the Buddha who is yet to come. Here was a tremendous and revolutionary movement in the new faith, the beginning of a long process. It was as though the Christians had taken the particular attributes, justice, mercy, etc., of God and, after personifying each one, deified it, thus multiplying gods. What was the soil for the new sowing, and what was the harvest to be reaped in due time? With many thousands of India Buddhists whose minds were already steeped in Brahministic philosophy and mythology, who were more given to speculation and dreaming than to self-control and moral culture, and who mourned for the dead gods of Hinduism, the soil was already prepared for a growth wholly abnormal to true Buddhism, but altogether in keeping with the older Brahministic philosophies from which these dreamers had been but partially converted to Buddhism.[18] The seed is found in the doctrine which already forms part of the system of the Little Vehicle, when it tells of the personal Buddhas and the Buddhas elect, or future Buddhas. In the Jataka stories, or Birth tales, "the Buddha elect" is the title given to each of the beings, man, angel, or animal, who is held to be a Bodhisattva, or the future Buddha in one of his former births. The title Bodhisattva[19] is the name given to a being whose Karma will produce other beings in a continually ascending scale of goodness until it becomes vested in a Buddha. Or, in the more common use of the word, a Bodhisattva (Japanese bosatsu) is a being whose essence has become intelligence, and who will have to pass through human existence once more only before entering Nirvana.
