Trataka, a technique used in a meditation practice, is one of the six purification techniques, called shatkarmas, of Hatha yoga. Trataka is a Sanskrit word, which means "to look" or "to gaze." As such, this meditation technique involves starting at a single point of focus. This is typically the flame of a candle, but other objects that may be used include a dot on the wall, an object of worship, a deity, flower, mountain, rising sun or moon. However, a flame is believed to work best. Especially an oil or a ghee lamp as they have a lot of energy
1. Light a ghee lamp and place it one hand distance from your eyes.
2. Gaze on the flame and do not blink. Your eyes will water. Hold as long as you can approx recommended time 10 - 15 minutes.
