Purankalsa Purnakalasa

Purankalsa Purnakalasa also known as Purnakumbha, Purnaghata and Mangalakalasa is one of the eight auspicious symbols of the Indian classical art.

It is a symbol of plenty and creativity.

This symbol is normally associated with Lakshmi and with over flowing foliage composed of lotus buds, flowers and leaves.

The motifs of Purankalsa appears in its finest form on the interiors of Taj Mahal. Here the vase and the foliage motif have been combined in a very fine way with the inner border.
