Jñanasattva (Skt. jñānasattva; Tib. ཡེ་ཤེས་སེམས་དཔའ་་, yeshe sempa, Wyl. ye shes sems dpa’), 'wisdom being', is:

1. The actual wisdom deities you invite to come and bless the deities of the mandala you have visualized.
2. It also refers to the deity visualized in the heart centre of the samayasattva.

The buddhas invited from [their buddha fields] are called “jñānasattvas” (wisdom beings) because they have abandoned all their obscurations, are complete with all good qualities, and have perfected their wisdom. Therefore they are called jnanasattvas.<ref>His Holiness Dilgo Khyentse Rinpoche, Pure Appearance—Development and Completion Stages in Vajrayana Practice (Halifax: Vajravairochana Translation Committee, 2002), page 71. restricted publication</ref>
