Tulsi Vivah, is observed at dusk in homes. The place is cleaned up and rangolis are drawn in front of Tulsi Vrindavan. Tulsi plant, being treated as the bride is smeared with turmeric and vermilion. Small bangles are hang on the tender branches. A small cloth is wound around the plant. A Shaligrama is placed next to the Tulsi as the symbol of Mahavishnu, the groom. A priest is summoned and all rites, involved in a formal wedding are conducted.
In some places, a cloth is held in front of the plant, which acts like a screen, while mantras are chanted. At the end of the mantra recitation, the cloth is removed as a mark of culmination of the wedding.
The performance of this pooja bestows prosperity, a cordial relationship between partners and all other material boons. When done with proper understanding of its essence, it bestows self realisation, the end of all spiritual pursuits.
