Rigpa is a Tibetan word, which in general means ‘intelligence’ or ‘awareness’. In Dzogchen, however, the highest teachings in the Buddhist tradition of Tibet, rigpa has a deeper connotation, ‘the innermost nature of the mind’. The whole of the teaching of Buddha is directed towards realizing this, our ultimate nature, the state of omniscience or enlightenment – a truth so universal, so primordial that it goes beyond all limits, and beyond even religion itself.[1] —Sogyal Rinpoche
