三密
The three mystic things: the body, mouth (i.e. voice), and mind of the Tathgata, which are universal, all things being this mystic body, all sound this mystic voice, and all thought this mystic mind. All creatures in body, voice, and mind are only individualized parts of the Tathgata, but illusion hides their Tathgata nature from them. The esoterics seek to realize their Tathgata nature by physical signs and postures, by voicing of 言 dhra and by meditations, so that 入我我入 He may enter me and I Him, which is the perfection of siddhi 悉地; v. 大日经疏 1. 菩提心论.
