Sarvajñatā

sarvajñatā (P. sabbaññu; T. kun shes/thams cad mkhyen pa; C. yiqie zhi 一切智). Translated as “all-knower,” “all-knowledge,” “omniscience,” etc.

The Princeton Dictionary states:

... in early versions of the perfection of wisdom (prajñāpāramitā) sūtras, the name for a buddha’s knowledge; later, the term was used for the knowledge of a sravaka or pratyekabuddha, in contrast to a buddha’s knowledge of all aspects (sarvākārajñatā), which is reached by cultivating a bodhisattva’s knowledge of the paths (mārgajñatā).

The “all” (sarva) means all the grounds (vastu) of the knowledge of defiled (saṃkliṣṭa) and pure (viśuddha, see viśuddhi) dharmas systematized in the Four Noble Truths.

The Tibetan translations for this term (kun shes and thams cad mkhyen pa) also the following meanings:

1. a general term for "omniscience"
2. an epithet for the Buddha
3. a title for a high lama
