In a second phase of this practice, a yogi hangs a picture of his chosen deity behind them so that its image appears in a mirror placed in front. Then the yogi scolds or praises the image as his self-reflection and sees if there is any emotional response. When there is no response, the yogi contemplates the illusory ("maya") nature of themselves and the reflection, feeling that everything is essenceless like the deity's body. This instruction is said to be a postmeditative practice and thus may have meant to be practiced in-between sessions of regular sitting meditation.
