Deepinder Goyal, Art of Living team up to study meditation using Temple
Deepinder Goyal’s health-tech venture Temple is teaming up with the Sri Sri Institute for Advanced Research (SSIAR), the research arm of Art of Living, to closely study the impact of different meditation practices on the body. According to Goyal, experienced meditators will use Temple while they meditate. Researchers will then track their Entropy levels in real time. The metric is said to measure the body’s metabolic and sympathetic activity, helping researchers compare the effects of different meditation practices on the body.
Goyal shared details of the collaboration on X after visiting the Art of Living ashram. “I am glad to have temple and Sri Sri Institute for Advanced Research (SSIAR), the research arm of Art of Living, collaborate to measure the effect of different meditation practices through Entropy,” he wrote. “Entropy is a new biomarker on temple that also measures your body’s (para)sympathetic state, and we have seen it drop real time during meditation, while HR stays flat,” he added. What is Temple and what does it measure?
As for the device itself, Temple is a jellybean-shaped wearable. Unlike a smartwatch or fitness band, it sits against the side of the forehead, around the temple — hence the name. According to Goyal, the device is designed to capture physiological signals linked to the brain and body, including cerebral blood flow, oxygenation, heart rate, cognitive load and Entropy.
Goyal described Entropy as the “real-time cost” of keeping the body alive. The team says Entropy is a live measure of the body’s metabolic and sympathetic activity that updates every second. Temple also distinguishes between Resting Entropy, or Entropy Minima, and Max Entropy, or Entropy Maxima.
But why the temple? The side of the forehead has thin skin, lots of blood vessels and very little movement compared with the wrist or hand. According to the company, measuring signals from the temple area could help the device capture cleaner and more accurate signals from the body.Temple has also shared its first brain blood-flow study
The meditation research comes shortly after Temple researchers shared a preprint looking at another key feature of the wearable, its ability to track brain blood flow.
In the study, researchers compared Temple’s Brain Flow reading with transcranial Doppler (TCD), an ultrasound method already used to measure blood flow in the brain. The study involved 23 healthy adults.
The researchers tested the participants while they were cycling, recovering from exercise, and changing positions from standing to lying down. They found that Temple’s Brain Flow readings changed in the same direction and at a similar time as the TCD measurements.When is Temple coming to India?
Temple is still moving towards a wider launch. In August, Goyal revealed that the latest version of the wearable is now less than half the size of the version previously shown. He called it the smallest wearable on the market by volume and said it was also the company’s most powerful version yet.
Goyal said limited-edition pre-orders would open soon, with shipments expected before the end of 2026. However, Temple has not yet announced a confirmed pre-order date or final consumer price.- EndsPublished By: Divya BhatiPublished On: Sep 14, 2026 13:11 ISTAlso Read | Apple rolling out iOS 27 today: Check new features, compatible iPhones and how to downloadAlso Read | After Trump rejects AI slowdown, Sam Altman says competition does not justify recklessnessAlso Read | Anthropic CEO Dario says AI companies have been telling lies, reveals real dangers of AI
