Devahuti expressed her happiness by uttering the word bata, for she knew that her husband was in a highly elevated, transcendental position and was under the shelter of yogamaya. As stated in Bhagavad-gita, those who are great souls, mahatmas, are not under the control of the material energy. The Supreme Lord has two energies, material and spiritual. The living entities are marginal energy. As marginal energy, a person may be under the control of the material energy or the spiritual energy (yogamaya). Kardama Muni was a great soul, and therefore he was under the spiritual energy, which means that he was directly connected with the Supreme Lord. The symptom of this is Krsna consciousness, constant engagement in devotional service. This was known to Devahuti, yet she was anxious to have a son by bodily union with the sage. She reminded her husband of his promise to her parents: I will remain only until the time of Devahutis pregnancy. She reminded him that for a chaste woman to have a child by a great personality is most glorious. She wanted to be pregnant, and she prayed for that. The word stri means expansion. By bodily union of the husband and wife their qualities are expanded: children born of good parents are expansions of the parents personal qualifications. Both Kardama Muni and Devahuti were spiritually enlightened; therefore she desired from the beginning that first she be pregnant and then she be empowered with the achievement of Gods grace and love of God. For a woman it is a great ambition to have a son of the same quality as a highly qualified husband. Since she had the opportunity to have Kardama Muni as her husband, she also desired to have a child by bodily union.
