Pemako is one of the main hidden lands concealed like a terma treasure by Guru Rinpoche. It lies partly in the Indian state of Arunachal Pradesh in northeastern India, and partly in Tibet. It is the Mandala of Vajra Yogini. The Devakotta Mountain is a river island within Pemako with the river circling it like a horse shoe. This is one of the most significant holy sites of the hidden land and lies entirely in India. For whoever makes one complete circumambulation of the Devakotta Mountain, the door to all lower rebirths will be closed. The merit created here by prostrating, offering lights, performing rituals and so forth is equivalent to that accumulated by performing these virtuous activities billions of times elsewhere.

Riu Tala.

For the Bhuddists Riu Tala is the paradise of Avalokiteshvara. Pilgrims come here annually for prayer and meditation. You have a great view of the Namche Barwa Range from here on a clear day.

According to the Adis, Eko Dumbing is the highest peak and all the hills are its descendents. They believe it is the sacred domain of the Snow God Jimu Tayeng. The Adi community comes to this sacred mountain to collect Emo (econite) in an elaborated ritualistic expedition called Disang. Many wildlife, flora and rare species of birds can be seen here.
