If you arrive to the temple late you can enter anytime. Most of it the bereaved
family will be present before the ceremony. Also the greetings of the family would
just to give your condolences. Always there will be a open casket. Also it is
appropriate for the guest to view the body because the Buddhism deems the viewing
of the body to be a valuable reminder of impermanence of life. When seeing the
body there are appropriate behaviors you have to conduct. Bow slightly toward the
body as a sign of appreciation of its lesson regarding impermanence.
