A vanaprastha who develops pure devotional service achieves the Supreme Lord, Krishna, while in the vanaprastha stage of life. One who does not become completely Krishna conscious, however, first goes to the planet Maharloka, or Rishiloka, and from there directly achieves Lord Krishna.
One achieves Maharloka, or Rishiloka, through strict observance of positive and negative regulations. However, without developing a taste for chanting and hearing the glories of the Lord (sravanam kirtanam vishnoh [SB 7.5.23]), it is not possible to achieve the perfect liberation of going back home, back to Godhead. Therefore, on the Maharloka planet the unsuccessful sage gives more attention to chanting and hearing, and thus he gradually develops pure love of Godhead.
