Having external contacts excluded, and with gaze fixed between the eyebrows; having made equal the outgoing and ingoing breaths moving within the nostrils;
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
This is the Gita’s first concrete meditation instruction, and it reads like a technical manual rather than philosophy: external contacts shut out, the gaze fixed at the point between the eyebrows, and prāṇa and apāna, the outgoing and ingoing breaths, deliberately equalized. Prāṇāyāma is being described here without yet being named, three verses before chapter 6 opens its own, far more detailed treatment of the same territory. This verse is best read as chapter 6’s advance trailer rather than a complete technique in itself, since it stops short of specifying a posture, a duration, or a place to practice.
