Trāṭaka (Sanskrit: त्राटक "look, gaze") is a yogic purification (ashatkarma) and a tantric method ofmeditation that involves staring at a single point such as a small object, symbol oryantra such as theOm symbol, black dot orcandle flame.[1][2][3]
Trāṭaka (Sanskrit: त्राटक), meaning “to gaze steadily,” is a classical yogic practice that combines visual concentration with meditative awareness. Traditionally, it is performed by fixing the eyes on a single external object—most often the flame of a ghee lamp or candle—without blinking until tears arise naturally. Ancient texts such as theHatha Yoga Pradipika andGheranda Samhita describe it as both ashatkarma (purificatory technique) and a meditation method, intended to cleanse the eyes, steady the mind, and prepare practitioners for deeper states of concentration.[4]
In modern contexts, Trāṭaka is interpreted not only as a spiritual discipline but also as a practical tool for cultivating attention and reducing mental distraction. Contemporary practitioners often use it as a bridge between mindfulness and traditional yoga, while researchers have begun to explore its cognitive and emotional effects through controlled studies.[5]
Both traditional accounts and modern research highlight potential benefits of Trāṭaka:
Cognitive performance: A 2021 study reported improved working memory performance (Corsi Block-Tapping Task) after a single Trāṭaka session.[6]
Emotional balance: EEG studies suggest increased neural complexity, associated with cognitive flexibility and adaptability.[7]
Eye relaxation: A 2023 tele-yoga study found significant reductions in visual strain and mind-wandering after two weeks of practice.[8]
Meditative depth: Traditional sources describe Trāṭaka as a preparatory practice for deeper meditation, enhancing visualization and single-pointed focus.[4]
Although promising, these findings are preliminary, and larger clinical trials are needed to confirm therapeutic applications.[5]
