XII The Idea of Pre-Existence
“If A Bikkhu should desire, O brethren, to call to mind his various temporary states in days gone by—such as one birth, two births, three, four, five, ten, twenty, thirty, fifty, one hundred, or one thousand, or one hundred thousand births,—in all their modes and all their details, let him be devoted to quietude of heart,—let him look through things, let him be much alone.”
—Akankheyya Sutta.
