Thoma in Kathmandu Bouddhanath

The thirteen pinnacles on the top symbolize that sentient beings have to go through the thirteen stages of spiritual realizations to reach enlightenment or Buddhahood.

There is a large pair of eyes on each of the four sides of the main stupa which represent Wisdom and Compassion. Above each pair of eyes is another eye, the third eye. It is said that when Buddha preaches, cosmic rays emanate from the third eye which act as messages to heavenly beings, so that those interested can come down to earth to listen to the Buddha. The hellish beings and beings below the human realm cannot come to earth to listen to the Buddha's teaching, however, the cosmic rays relieve their suffering when Buddha preaches.

There are carvings of the Panch Buddhas (five Buddhas) on each of the four sides of stupa. There are also statues of the Buddhas at the base of the stupas. Panch Buddhas are Buddha in metaphorical sense in Tantrayana. They are Vairochana (occupies the center and is the master of the temple), Akshobhya (faces the east and represents the cosmic element of consciousness), Ratna Sambhava (faces the south and represents the cosmic element of sensation), Amitabha (He represents cosmic element of Sanjna (name) and always faces the West) and Amoghsiddhi (He represents the cosmic element of conformation and faces the north).

Each morning before dawn hundreds of Buddhist (Vajrayana) and Hindu pilgrims ascend the 365 steps from eastern side that lead up the hill, passing the gilded Vajra (Tibetan: Dorje) and two lions guarding the entrance, and begin a series of clockwise circumambulations of the stupa.
