Therefore I should now give up my attachment for things created by the external energy of the Supreme Personality of Godhead. I should engage in thought of the Lord and should thus surrender unto Him. This material creation, having been created by the external energy of the Lord, is like an imaginary town visualized on a hill or in a forest. Every conditioned soul has a natural attraction and attachment for material things, but one must simply give up this attachment and surrender unto the Supreme Personality of Godhead.
