Kāraṇa / Causal Ocean

The Kāraṇa, or Causal Ocean, is closely associated in the chart with the boundary, though texts may use the two terms with different nuances. Kāraṇodakaśāyī Viṣṇu reclines within it, beyond any single material universe — the ocean the material creation as a whole rests in, prior to any one universe taking shape within it.
