Kardama Muni was anxious about his good wife, Devahūti, while leaving home, and so the worthy son promised that not only would Kardama Muni be freed from the material entanglement, but Devahūti would also be freed by receiving instruction from her son. A very good example is set here: the husband goes away, taking the sannyāsa order for self-realization, but his representative, the son, who is equally educated, remains at home to deliver the mother.
