4.367

第三喻中，水喻離喜無尋伺定乃至喻華胎藏沒在水中者，此言意顯，第二定如水，因喜動涌如華出水華喻喜故，今第三定離喜無尋伺亦如水，其樂如華胎藏胞未開剖，猶在水中名華胎藏，與定相順不動湧故如在水中。

In the third simile, 'water' is a simile for the concentration free from joy and without investigation or reflection, down to 'like a lotus calyx submerged in water': this phrasing intends to reveal that the second concentration is like water; agitated and welling up due to joy, it is like a flower emerging from water, the flower being a simile for joy. Now the third concentration is free from joy and without investigation or reflection, which is also like water; its bliss is like a lotus calyx whose bud has not yet split open, still remaining in the water, named 'flower calyx'—because it accords with concentration and does not surge or well up, it is like being in water.
