According to Gampopa's "Closely Stringed Pearls", the practice of Illusory Body ("sgyu lus, *mayadeha or *mayakaya") is done by assuming a meditative posture and meditating by looking at one's body in a mirror, contemplating how it has an illusory nature. According to Kragh, "He should then speak to himself, voicing many self-criticisms and check whether he feels any unhappiness or expressing praises and see whether he feels pleased. As long as such emotions arise, he has not trained himself sufficiently in the practice. Once no emotion occurs, he should contemplate all appearances of himself and everything else as having a hallucinatory and dream-like quality." Another meditation manual by Gampopa states that one should meditate on reality as being dreamlike before doing the mirror practice.
