Another quality of the Bodhisattva is their freedom from fear ("na √tras") in the face of the seemingly shocking doctrine of the emptiness of all dharmas which includes their own existence. A good friend ("kalyanamitra") is useful in the path to fearlessness. Bodhisattvas also have no pride or self-conception ("na manyeta") of their own stature as Bodhisattvas. These are important features of the mind of a bodhisattva, called bodhicitta. The Prajñāpāramitā sutras also mention that bodhicitta is a middle way, it is neither apprehended as existent ("astitā") or non-existent ("nāstitā") and it is "immutable" ("avikāra") and "free from conceptualization" ("avikalpa").
