Lord Vishnu was very much saddened by the death of Vrinda. He took the ashes from the pyre and after applying them on his body started wondering here and there.
The deities became very worried to see the condition of lord Vishnu. They went to lord Shiva and requested him to eliminate the false attachment with which Sri Vishnu was suffering.
Lord Shiva sent the deities to goddess Parvati, saying that she would ceratainly help in this regard.
The deities went to goddess Parvati and prayed to her. She became very pleased and with the assistance of Lakshmi and Saraswati, gave some seeds to then. The deities sprayed those seeds on the pyre, on which Vrinda had given up her life. Three holy plants manifested from that pyre- Amla, Tulsi and Malti. Later on Tulsi and Malti attained to the Vishnuloka, by the virtue of their respective penance.
