It should be realised that there is room in the heart for only a single person. It is not to be regarded as a double sofa or a musical chair. God alone should be installed in the heart. It is because people change their loyalties from moment to moment that their devotion is diluted and their aspirations remain unfulfilled. With a pure heart and one-pointed devotion, anything can be achieved.
-Divine Discourse, 3rd April 1990.
