Due to the holiness of Tulsi, she is considered the most beneficial in worshipping Lord Vishnu. Lord Vishnu has immense affection for Tulsi, and if Tulsi leaves are not easily available, then a garland made of Tulsi woods can be used.
Skanda Purana mentions the importance of Tulsi to Lord Vishnu:
Manikanchan pushpani muktamayani cha Tulsidalmatrasya kalam narhanti shodasim
The offering of garlands, even those made of gold and diamonds or pearl-like flowers, are not enough to please Lord Vishnu in all his sixteen moods as much as a leaf of Tulsi can do easily.
Padma Purana also talks about Lord Vishnu’s fondness for Tulsi:
Lord Vishnu keeps away from being worshipped, even with a garland full of virtues. But worshipping him with Tulsi pleases him with the small amount that has been offered.
Mythology says that Tulsi was the wife of a demon named Shankhchud. She had great liking for Lord Krishna in her previous birth and had practiced asceticism to find him. Lord Brahma advised her to marry Shankhchud and also disclosed to her that she would marry Lord Krishna in the future. Heeding the advice of Lord Brahma, Tulsi married Shankhchud. After this marriage Tulsi and Shankhchud lived with love. Tulsi was a pious lady. Shankhchud was the master of demons. He wore the shields given by Lord Vishnu. This shield along with Tulsi’s piety had left him ndefeated in wars.
One day on the behest of Lord Vishnu, Lord Shiva attacked Shankhchud. A fierce battle broke out between the two. Shankhchud could not be defeated. The gods thought that till Shankhchud kept the shield of Lord Vishnu and the piety of his wife was not broken, he could not be defeated. Thinking about the strength of Shankhchud and on the request of Lord Shiva, Lord Vishnu went to Shankhchud wearing an old person’s garb and demanded his shield as alms. Shankhchud gave away his shield to this man (who really was Lord Vishnu). After wearing the shield, Lord Vishnu went to Tulsi and appeared in the guise of Shankhchud and announced his victory. Tulsi was thus tricked by Lord Vishnu; and taking Vishnu as her husband, she worshiped him with love. Lord Vishnu had broken her piety and he was able to crush Shankhchud in the battle that ensued.
When Tulsi came to realize that she was deceived and that the person before her was not Shankhchud but somebody else, she became furious with Lord Vishnu and cursed him to become a stone. Upon hearing Tulsi’s curse, Lord Vishnu appeared in his actual form and told her that she had offered prayers to him. Therefore she should not repent for what had taken place. He advised her to leave the body and live with him as Goddess Lakshmi. Then he ordained that she would always remain present on earth in the form of river Gandaki and the Tulsi plant. The Lord would always be present near river Gandaki as a stone by the name of Shaligram. Tulsi would be the most pious plant in the entire universe. Prayers to Lord Vishnu would not be complete until Tulsi was present.
Lord Vishnu married Tulsi on the full moon day of Kartika month. Due to this mythological belief, the wedding ceremony of Tulsi with Lord Vishnu is celebrated in Hindu homes on the full moon day of Kartika month.
It is advised that the person fasting for Tulsi’s wedding must plant Tulsi and worship her for three months before Kartika. Ceremonial programs associated with her marriage should start from Prabodhini Ekadashi of Kartika Shukla. Then onthe full moon day of Kartika month, Strachchhed (a symbolic platform for wedding rituals and a tradition from the Puranic age) is made and four priests start the ceremony by worshipping of Ganapati-Matrikas. Shaligram and Tulsi are seated on a golden or silver seat looking towards the east.
The couple performing this ceremony should sit like ascetics looking towards the north and then they should worship the sacred fire and give away clothes and jewels as alms. After having completed the entire prayer ceremony, food should be taken after offering it to the priests.
One who celebrates the wedding of Tulsi with Lord Vishnu in the established system of rituals is considered a great devotee of Lord Vishnu and will always feel protected.
