The first condition of devotional service
There is a common saying that one should first love the dog of the beloved before one shows any loving sentiments for the beloved. The stage of pure devotion is attained by sincerely serving a pure devotee of the Lord. The first condition of devotional service to the Lord is therefore to be a servant of a pure devotee, and this condition is fulfilled by the statement “reception of the dust of the lotus feet of a pure devotee who has also served another pure devotee.” That is the way of pure disciplic succession, or devotional parampara.
