— taking refuge in that (state); — by the upward path; — moon and sun (iḍā and piṅgalā / prāṇa and apāna); — both; — in the suṣumnā channel; — having gone to setting (dissolved); — having abandoned; — the range of the cosmic egg
Resting in that (Spanda), both sun and moon, journeying upward through the suṣumnā path, set within it, abandoning the sphere of the cosmic egg.
