Samyak Darshan Pad (the sixth Pad of Navapad/Siddhachakra) is the pad to worship to develop right faith.

• In Navapad, the six Pad is Samyak Darshan, meaning Right Faith or Right View. This Pad is considered the root of all Dharma and the starting point for spiritual progress. Worship or remembrance of Samyak Darshan helps cultivate the correct faith in the teachings of the Arihant, Guru, and scriptures. This is traditionally emphasized during Navpad Oli (Navapad Ayambil).
