Mbh 13.4.3b

Of thee too shall be born a mighty and glorious son who, endued with virtue, shall perpetuate my race. Truly do I say this unto thee! When you two shall bathe in your season, she shall embrace a peepul tree, and thou, O excellent lady, shalt likewise embrace a fig tree, and by so doing shall ye attain the object of your desire. O sweetly-smiling lady, both she and you shall have to partake of these two sacrificial offerings (charu)[8] consecrated with hymns, and then shall ye obtain sons (as desired).'--At this, Satyavati, delighted at heart, told her mother all that had been said by Richika as also of the two balls of charu. Then the mother, addressing her daughter Satyavati, said:--'O daughter, as I am deserving of greater consideration from thee than thy husband, do thou obey my words. The charu, duly consecrated with hymns, which thy husband has given to thee, do thou give unto me and thyself take the one that has been prescribed for me. O sweetly-smiling one of blameless character, if thou hast any respect for my word, let us change the trees respectively designed for us. Every one desires to possess an excellent and stainless being for his own son. The glorious Richika too must have acted from a similar motive in this matter, as will appear in the end. For this reason, O beautiful girl, my heart inclines towards thy charu, and thy tree, and thou too shouldst consider how to secure an excellent brother for thyself.'--The mother and the daughter Satyavati having acted in this way, they both, O Yudhishthira, became big with child. And that great Rishi, the excellent descendant of Bhrigu, finding his wife quick with child, was pleased at heart, and addressing her, said,--'O excellent lady, thou hast not done well in exchanging the charu as will soon become apparent. It is also clear that thou hast changed the trees. I had placed the entire accumulated energy of Brahma in thy charu and Kshatriya energy in the charu of thy mother.
