Sau Seng Lum also initiated and installed Three Sages in Saha World within the temple. The three sages are Śākyamuni Buddha, Kṣitigarbha Bodhisattva and Goddess of Mercy Bodhisattva.

These three sages always manifest in Saha World to teach and rescue sentient beings, and thus created great affection and affinity with earth and embracing principal and subsidiary causes. They are therefore called Three Sages in Saha World.
