Prasrabhi

Prasrabhi (Sanskrit; Tibetan Wylie: shin tu sbyang ba) is a Mahayana Buddhist term translated as "pliancy", "flexibility", or "alertness". It is defined as the ability to apply body and mind towards virtuous activity. It is one of the virtuous Mental factors within the Abhidharma teachings.

The Abhidharma-samuccaya states:

What is alertness? It is the pliability of body and mind in order to interrupt the continuity of the feeling of sluggishness in body and mind. Its function is to do away with all obscurations.
