Kaushalya and his other beloved consorts were all of holy life; humble and devoted to their Lord,
They had strong attachment to the lotus feet of Lord Vishnu,
One day the king was sad at heart that he had no SON-he hastened to his preceptor's residence and falling at his feet, made many entities,
He told the guru all his joy and sorrows-the sage Vasistha comforted him in many ways and said take heat and wait--you will have four sons, who will be known throughout the three worlds and will rid the devotees of their fears,
May Lord bless all,
Thanks please
