Many believe that humans have the memory of a goldfish, about 8 seconds, though not everyone agrees. Health experts agree that improving concentration and calming the mind can help boost memory and focus. One ancient technique that promises both is candle gazing meditation, or trataka. Rooted in traditional yogic practices, this method involves focusing on a candle flame to enhance cognitive function, mental well-being, and spiritual awareness. But how does it work? And is it safe for your eyes? Here is what experts and research reveal about this time-honored practice.What Is Candle Gazing Meditation?Candle gazing meditation, or trataka, is a yogic technique mentioned in classical Indian texts such as the Hatha Yoga Pradipika. In Sanskrit, “trataka” means to look or gaze, signifying the practice’s emphasis on sustained visual concentration."People today are constantly distracted," says Nisha Saini, a board-certified holistic health practitioner and founder of the New York Ayurveda & Panchakarma Center. “We’ve forgotten how to relax. Focusing on a single object, like a candle flame, helps empty the mind and restore calm.”Historical And Ayurvedic PerspectiveTrataka has been an integral part of yogic and Ayurvedic traditions for centuries. Ancient texts suggest that this practice was used for purification, mental clarity, and even eye health. Ayurveda categorizes the body into three doshas—Vata (air and space), Pitta (fire and water), and Kapha (earth and water)—and associates the fire element with cognition and focus.Pierre Couvillion, director of the Santosha School in Indianapolis, explains, "Fire is linked to the brain’s gray matter and the ability to process information. Candle meditation refines this element, enhancing mental clarity and perception."Potential Benefits of Candle Gazing MeditationExperts and some studies suggest that candle gazing meditation may offer several cognitive and health benefits:Enhanced focus and cognitive function: Research indicates that trataka improves working memory, spatial attention, and selective focus.Improved mental health: Meditation is widely known for reducing stress and anxiety. Trataka, in particular, helps calm the mind by engaging the third eye chakra, which is associated with intuition and insight.Better sleep: A small 2020 study found that practicing trataka for 10 days improved sleep quality and reduced insomnia severity.Possible eye health benefits: While traditional texts claim trataka can prevent eye diseases, scientific research on this is mixed. Some studies suggest it may help with intraocular pressure in glaucoma patients, while others found no significant impact on myopia.How To Practice Candle Gazing MeditationIf you are interested in trying candle gazing meditation, follow these steps:Choose a quiet, dimly lit space.Place a candle at eye level and sit in a comfortable position.Take deep breaths and set an intention.Focus on the candle flame, trying not to blink frequently.Observe your thoughts without engaging with them.If your eyes water, allow it to happen—it is considered a cleansing effect.Finish your session with gratitude.Beginners can start with just one to five minutes, gradually increasing duration as focus improves. Experts recommend morning sessions for enhanced concentration, while nighttime practice may aid sleep.Is Candle Gazing Meditation Safe?For most individuals, candle gazing meditation is safe. However, it may not be advisable for those with severe eye conditions, psychosis-related disorders, or a history of seizures. It is always best to consult a healthcare professional before starting any new meditation practice.
