Yidam.

Quotes.

'Yidam (Tibetan): Buddha form. One of the Three Roots. Source of enlightened qualities.'

-- Quoted from 'The Way Things Are' book by Lama Ole Nydahl.


'Buddha Form / Buddha Aspect (Tibetan: Yidam; Sanskrit: Istadevata): One of the Three Roots. The limitless qualities of the enlightened mind express themselves in countless forms of energy and light. When one uses them in meditation and in daily life, they awaken the inherent buddha nature in everyone. They are seen as inseparable from one's own lama. In order to meditate on them, one needs permission or the empowerment from a lama who holds their transmission.'
