I travelled in Tibet and was allowed into a morning prayer ceremony. Hours of chanting left me calm and relaxed. Yak butter was melting everywhere on altars. The scent brings back the inner peace. I have a recording of the ceremony but it doesn't do it. One of the treasures I brought back smells of yak butter. And yes there are Tibetan stores and restaurants in Jackson Heights that carry it. Next Mudcat get together I will bring some.
