Grammatical Analysis
Ogha: [m.] flood; torrent; inundation. Traditionally derived from root vah (to carry away, sweep away), denoting a violent rush of water that drowns beings and sweeps them out to the ocean of saṃsāra.
Orthodox Definition
In the Abhidhamma and Sutta classifications, the Oghas represent four specific manifestations of unwholesome defilements, grouped together because of their terrifying, sweeping, drowning psychological power. Doctrinally, they are absolutely identical in composition to the four Āsavas (taints) and the four Yogas (yokes).
The four floods are:
- Kāmogha: The flood of sensual desire.
- Bhavogha: The flood of desire for existence.
- Diṭṭhogha: The flood of wrong views.
- Avijjogha: The flood of ignorance.
The commentaries note that while āsava emphasizes the fermenting, deep-seated toxicity of defilements, ogha is used to emphasize their overwhelming, kinetic violence—showing how beings are violently swept away by lust, views, and blindness, entirely unable to reach the safe “further shore” (pāraṃ) of Nibbāna.
