The mandaa:/ mandala of Janabaha is an important spiritual and artistic element within the monastery courtyard. In Newar Buddhism, a mandaa: symbolizes the universe, divine order, and the sacred path toward enlightenment. It is not simply an artwork but a spiritual diagram used for meditation, rituals, and worship.

At Janabaha, the mandaa: reflects the Vajrayana Buddhist tradition followed by the Newar community of the Kathmandu Valley.
