Remnants of age-old customs still adopted by a few Chinese families
in prayers to deities and ancestors, burning paper clothing and money
for and offering food to those already departed carry no Buddhist
connotations whatsoever and are nowhere mentioned in the Tripitaka.
Neither are they ever done even in India. Such customs are but
exhibitions of sentiments mired in misconceptions of the dead still
being in need of anything material. The Buddha had never spoken
about any of them.
