In the Theravada tradition, it is customary to pay homage to the Buddha, recite the Three Refuges and undertake to observe the Pancca Sila (Pansil) on visiting a place of worship or at the start of a Buddhist ceremony. One can recite the following stanzas by oneself or invite a Buddhist monk to administer them.

The monk will recite each stanza in the ancient language of Pali and the devotee should repeat it after him.

The meaning of "Namo Tassa Bhagavato arahato samma sambuddhassa" is:
Honour to the Blessed One, the Exalted One, the fully Enlightened One
