This sacred ash for meditation comes to us from the Dhyanalinga temple at the Isha Yoga Center in Coimbatore, India. It is traditionally applied on the forehead between the eyebrows.

"Certain substances have been identified as substances that can easily gather and retain energy. Vibhuti is one which is very highly sensitive. You can easily energize it and give it to someone. Kumkum is also like that. Sandal paste, is also like that to some extent, but I would definitely put vibhuti on top of the list in terms of conductivity." -Sadhguru
