In fact, the aspirations of few pious Buddhists in early times ever led them to soar higher than the happiness of living with Maitreya and listening to his voice in his own Tushita heaven. It is true that afterwards when the worship of the Dhyāni-Buddha Amitābha came into vogue in Northern countries this Buddha’s heaven, called Sukhāvatī, fabled to be somewhere in the Western sky, seems to have taken the place of the heaven of Maitreya. But this belongs to a later phase of Buddhism, to be explained when we speak of the Dhyāni-Buddhas (p. 203). It was for Maitreya’s Tushita heaven that Hiouen Thsang, and other devout men of his day, prayed on their death-beds, and the one Chinese inscription found at Buddha-Gayā is full of expressions indicative of the same longing[87]. If then, we are able to enter into the feelings of Buddhists everywhere in depending on the living, loving, and energizing Maitreya, rather than on the extinct Buddha who existed only in their memories, we shall find it less difficult to understand how it came to pass that the idea of, so to speak, canonizing every great saint or popular head of a monastic community, and elevating him at death to the position of a Bodhi-sattva like Maitreya, living in permanent regions of bliss, and able to help his votaries to the same position, came into vogue. It may make the course of development of Theistic Buddhism clearer if we here revert to the early constitution of the Buddhist monastic brotherhood, and endeavour to show how the homage paid to eminent and saint-like men led, first to the multiplication of Bodhi-sattvas, and then to polytheism and every form of polytheistic superstition. A full explanation of the early monastic system is given in the learned work of Koeppen[88]. It is clear that as long as Gautama was alive he was the sole Head of the brotherhood of monks. After his death the Headship (as in the Christian brotherhood after the death of Christ) was not assigned to any one leader. The Buddha himself forbade this. The term Saṇgha at that time merely denoted a republican fraternity of monks, bound by no irrevocable vows and subject to no hierarchical Superior, but all intent on following the example, and propagating the doctrines of their departed leader. Soon, however, the formation of separate centres of union and teaching became inevitable, and the term Saṇgha was then applied to each separate society, and sometimes even to a separate Conclave of each society, as well as to the whole body. It seems at least certain that each monastic association had the right to admit monks, to hear confession, and to excommunicate. Naturally, too, in course of time it became necessary for each society to have some sort of governing body and choose a kind of president, and this presiding officer was originally the senior monk, and accordingly had the simple title of Sthavira (Thera), ‘Elder.’ This title appears to have been introduced immediately after Gautama’s death.
