What Is Vastra?
Vastra means “clothing” in Sanskrit.
The seventh of sixteen customary upacharas("offerings") made to a god as part of devotion, based on the
principle of honoring the deity as a distinguished guest.
The god is clothed with this offering, either by symbolic presentation or literally dressing the picture.
The fundamental aim, like with other upacharas, is to
demonstrate one's affection for the god and to minister to the deity's
necessities.
