Mantra Chanted By Mata Sita in Ramcharitmanas
तौ भगवानु सकल उर बासी।
करिहि मोहि रघुबर कै दासी।।
जेहि कें जेहि पर सत्य सनेहू।
सो तेहि मिलइ न कछु संदेहू।।
करिहि मोहि रघुबर कै दासी।।
जेहि कें जेहि पर सत्य सनेहू।
सो तेहि मिलइ न कछु संदेहू।।
Tho Bhagavnu Sakal Ur Basi
Karihi Mohi Raghubar Ke Dasi
Jehi Kem Jehi Par Satya Snehu
So Tehi Mili Na Kuch Samdeh
The story behind the Mantra
Mata Sita had wedded Lord Sri Ram in her mind. But Janaka, her father, had kept the condition that only a person who will lift the bow of Shiva in his palace and tie it will get the hand of Mata Sita in marriage.
Mata Sita doubted whether someone will lift the bow before the arrival of Bhagavan Sri Ram.
So she offered prayers stating that if my love and devotion for Sri Ram is true then only He should marry me.
