This is the process of renunciation at the stage of vanaprastha. After enjoying householder life for some time, the husband and wife must leave home and distribute their riches to brahmanas and Vaisnavas. One can keep his wife as an assistant in the vanaprastha stage. The idea is that the wife will assist the husband in spiritual advancement. Therefore Narada Muni advised the hunter to adopt the vanaprastha stage and leave home. It is not that a grhastha should live at home until he dies. Vanaprastha is preliminary to sannyasa. In the Krsna consciousness movement there are many young couples engaged in the Lord's service. Eventually they are supposed to take vanaprastha, and after the vanaprastha stage the husband may take sannyasa in order to preach. The wife may then remain alone and serve the Deity or engage in other activities within the Krsna consciousness movement.
