And again, O King, just as the diamond is set together with the most costly gems; just so, O King, should the strenuous Bhikshu, earnest in effort, associate with those of the highest excellence, with men who have entered the first or second or third stage of the Noble Path, with the jewel treasures of the Arahats, of the recluses of the threefold wisdom, or of the sixfold insight. This, O King, is the third quality of the diamond he ought to have. For it was said, O King, by the Blessed one,[355] the god over all gods, in the Sutta Nipâta: Let the pure associate with the pure, Ever in recollection firm; Dwelling harmoniously wise, Thus shall ye put an end to griefs. The description of the New Jerusalem in the book of Revelations finds a curious parallel in the Hindu Puranas. Here we are told that the divine Krishna, the eighth incarnation of Vishnu, took up his abode in the wonderful city Devârakâ, and was visited there by the various orders of gods and geniuses.[356] Gods, Asuras, Gandharas, Kinnaras began to pour into Dwáraká, to see Krishna and Valaráma. Some descended from the sky, some from their cars—and alighting underneath the banyan tree, looked on Dwáraká, the matchless. The city was square,—it measured a hundred _yojonas_, and over all, was decked in pearls, rubies, diamonds, and other gems. The city was high,—it was ornamented with gems; and it was furnished with cupolas of rubies and diamonds,—with emerald pillars, and with court-yards of rubies. It contained endless temples. It had cross-roads decked with sapphires, and highways blazing with gems. It blazed like the meridian sun in summer. As compared with the description in Revelations we cannot fail to note the lack of definiteness. Instead of the well-ordered scheme of color as represented by the twelve precious stones dedicated to the twelve tribes of Israel, the mystic Hindu city is simply a gorgeous mass of the most brilliant gems known in India.
