Five inexhaustible wheels of ornaments
The five inexhaustible wheels of ornaments (Wyl. mi zad pa rgyan gyi 'khor lo lnga) or inexhaustible wheels of ornaments of body, speech, mind, qualities and activities (Wyl. sku gsung thugs yon tan phrin las mi zad pa rgyan gyi 'khor lo) is Highest Yoga Tantra terminology used to express enlightenment, the complete fruition of Tantra vehicle, and often used to talk about the body, speech and mind of the lama.
It is a way to describe ‘those’ who have attained the full perfection of awakening by mentioning their qualities: enlightened body, speech, mind, qualities and activities. "Wheel" refers to their all-encompassing qualities, as they pervade everything that there is. Traditionally "wheel" has the sense of inexhaustible as in principle it can always turn on the ground and the distance it covers is not limited by itself. “Ornaments” refers to the display of these qualities, body, speech, mind, qualities, and activities. “Inexhaustible” refers to the fact they are always benefiting sentient beings, constantly, and endlessly.
