A devotee can always try to fix his mind on service to the Deity form of the Lord, and when the mind becomes steady in such service, the Lord will reciprocate by arranging for His devotee to personally serve His arca-vigraha form. As in the example of Madhavendra Puri, Lord Gopal arranged everything so that Madhavendra Puri could serve Him.
