Four activities 四事業（息、增、懷、誅）
Four activities (Wyl. las bzhi) — the four activities of pacifying, enriching, magnetizing, and subjugating, which are practised as part of the deity yoga of the inner or higher tantras. Practitioners visualize themselves in the form of the deity and train in:
- pacifying conflict, sickness and famine;
- increasing longevity and merit;
- magnetizing the three realms and
- subjugating hostile forces,
often through the emanation of rays of light.
Once accomplishment has been reached, these four activities are carried out directly as aspects of enlightened activity for the benefit of others.
