Absolute bodhichitta

Absolute bodhichitta (Skt. paramārtha cittotpāda; Wyl. don dam sems bskyed) - the wisdom that directly realizes selflessness. It only arises through the power of meditating on the path, and is therefore known as ‘subtle bodhichitta, which is gained through reality itself.’

Kamalashila's Intermediate Stages of Meditation says:

Absolute bodhichitta transcends the mundane; it is beyond all limitations; it is utterly clear; it is the absolute domain; it is stainless and unmoving, like a candle flame undisturbed by wind. To achieve it, we must devote ourselves for a long time to training in the practices of shamatha and vipashyana.
