Illusory body

Illusory body is term for one of the Six Yogas of Naropa, also called luminosity. In his commentary, Pema Karpo says that the clear light is experienced briefly by all human beings at the very first moment of death, by advanced yogic practitioners in the highest states of meditation, and unceasingly by all Buddhas.

Luminosity or clear light (Tibetan: འོད་གསལ་, Wylie: 'od gsal, THL: ö-sel; Sanskrit: prabhāsvara), is a central concept in Esoteric Buddhism, Tibetan Buddhism and Bon. It is the innate condition of the mind, associated with buddha-nature, the realisation of which is the goal of meditative practice. It is said to be experienced when the coarse and subtle minds dissolve during deep sleep, during orgasm, and during the death process. All systems of Tibetan Buddhism agree that the clear light nature of mind is non-conceptual and free from all mental afflictions, and that tantra is the superior method of working with this nature of the mind.

Various Vajrayana practices involve the recognition of this aspect of mind in different situations, such as dream yoga. In this case, the practitioner trains to lucidly enter the deep sleep state. If one has the ability to remain lucid during deep sleep, one will be able to recognize the luminosity of death and gain Buddhahood. This is called the meeting of mother and child luminosities, resulting in the state of thukdam at death.
