Trataka (fixed gazing)

Trataka is a yogic practice of steady, unblinking gazing at a single point or object, used to develop concentration, still the restless mind, and, in the traditional accounts, to awaken inner vision. The practitioner fixes the eyes on a chosen object, most commonly the small steady flame of a lamp or candle, but also a dot, a symbol, an image of a deity, or the rising sun or moon, and holds the gaze without blinking for as long as is comfortable, until the eyes water, then closes them and holds the after-image of the object in the mind's eye. The outward gazing trains the eyes and gathers the attention onto one point; the inward visualisation that follows carries that gathered attention into the mind, and the two together are said to build a powerful one-pointedness of concentration.

The practice is classified in the hatha yoga tradition among the shatkarmas, the six purificatory actions, where it is credited with cleansing and strengthening the eyes; but its deeper purpose is meditative. By giving the notoriously restless mind a single fixed object, trataka is used as a preparation for meditation proper and as a technique for developing focus, and the traditional texts associate its sustained practice with the steadying of the mind, the awakening of concentration, and the arising of inner light and, in some accounts, of subtle perception. It has been widely taken up in modern yoga and meditation instruction as an accessible concentration exercise, generally taught with the caution that the gazing should not strain the eyes and should be built up gradually.

What trataka was originally for and what it is mostly used for today are two different things, and the gap between them is a useful case of a physical practice being kept while its stated purpose changed underneath it. The classical hatha yoga texts, the Hatha Yoga Pradipika and the Gheranda Samhita among them, group trataka with five other cleansing procedures, the shatkarmas, alongside practices for clearing the nasal passages, the stomach and the bowels, and describe its benefit in almost entirely physical terms: it is said to cure eye disease and induce a specific clarity of vision, and the texts treat it as bodily preparation clearing the way for pranayama and meditation rather than as a meditative technique in its own right.

Modern yoga and meditation teaching, particularly as transmitted through twentieth-century figures who reframed hatha yoga for a psychologically minded Western audience, has shifted the emphasis almost entirely onto the second half of the exercise, the closed-eye retention of the after-image, treating that moment as the point of the practice rather than an incidental effect of eye fatigue, and presenting trataka chiefly as a concentration and visualisation training exercise comparable to other one-pointed attention techniques rather than as a purification of the eyes. Contemporary teachers rarely cite the disease-curing claims of the classical texts at all, which makes trataka one of the clearer instances in yogic practice of a technique surviving intact while the tradition's own stated rationale for it was quietly replaced by a different one better suited to how it is actually being used now.
