釋禪波羅蜜次第法門 10.92

10.92

今修此定，既定觀均等，定深智利。定深故，在緣則不散；智慧利故，則進入捷疾無閡。是故從一禪起入一禪時利疾，心心相次，無諸雜間，隨念即入，亦名無間三昧。行者若用此心遍入諸禪，非但次第調柔，心無雜間，亦復增益諸禪功德轉深微妙，如鍊金，光色更增，價直亦倍，故說此定名曰鍊禪。

Now, when cultivating this absorption, since absorption and contemplation are equalized, absorption is deep and wisdom is sharp. Because absorption is deep, it does not scatter when on an object; because wisdom is sharp, progress is swift and unhindered. Therefore, when arising from one dhyāna and entering another dhyāna, it is sharp and swift, mind following upon mind without any intervening thoughts; one enters immediately upon a thought. This is also called uninterrupted samādhi. If practitioners use this mind to enter universally into the various dhyānas, not only are they sequentially pliant and their minds free of intervening thoughts, but they also increase the merits of the various dhyānas, making them ever deeper and more subtle. Just as in smelting gold, its luster and color increase further and its value doubles; therefore, this absorption is called refined dhyāna.
