What we have now stated is tolerably clear and intelligible; but what follows is less evident. It partakes of that obscurity and complication so peculiar to Buddhist metaphysics. This state of things is created and maintained chiefly by a mania for divisions and subdivisions that would have puzzled even the schoolmen of the middle ages. We have to listen to what our author says respecting the method to be observed in carrying on the great examination of all subjects of investigation. If that labour be patiently and perseveringly prosecuted until all the objects of inquiry be exhausted, ample and magnificent shall be the reward for such labours. The sage will be in possession of the perfect science; Neibban will appear to him; he will long for it, and unremittingly shape his course in its direction: in a word, he shall have reached the acme of perfection. Seated on that lofty position, enjoying a perfect calm in the bosom of absolute quietism, the sage is beyond the reach of passions; there is no illusion for him; he has cut the last thread of future generations by the destruction of the influence of merits and demerits; he has obtained the deliverance from all miseries; he has reached the peaceful shores of Neibban. But such a prize is not easily obtained; it is to be purchased only at the expense of an immense amount of lasting and strenuous mental exertion. The sage, agreeably to the old and always true saying, Know thyself, very properly begins his mightily difficult task with the examination of the five aggregates constituting a living being, the organs of the six senses, and all that relates to them. Then he applies himself to the studies of the five Dzan, or the parts of meditation and contemplation, and to all that is connected with the seats of Rupa and Arupa. All the objects of examination ranged on that scale are 600 in number. We shall rapidly glance over this table, indicating but the heads of the principal divisions. We ought not to forget that the five aggregate, or _khandas_, constituting a living being, are form, sensation, perception, consciousness, and intellect. Supposing that we take the first of those attributes as subject of examination. We must represent it to the mind, carefully examine it in all its bearings and properties, respecting the past, the present, and the future. We must proceed on and bring it in contact with the three great principles of aneitsa, duka, and anatta, and inquire whether form be changeable or not, passive or impassive, transient or permanent. We thereby acquire the knowledge of the following great truth; viz., form is essentially liable to change, pain, and illusion. The examination of each of the four other attributes is proceeded on in a like manner, and a similar result ensues.
