Srila Dhruva Maharaja realized that this cosmic manifestation bewilders living entities like a dream or phantasmagoria because it is a creation of the illusory external energy of the Supreme Lord.
In the deep forest sometimes it appears that there are big palaces and nice cities. That is technically called gandharva-nagara. Similarly, in dreams also we create many false things out of imagination. A self-realized person or a devotee knows well that this material cosmic manifestation is a temporary illusory representation appearing to be truth. It is like a phantasmagoria. But behind this shadow creation there is reality-the spiritual world. A devotee is interested in the spiritual world, not its shadow. Since he has realization of the supreme truth, a devotee is not interested in this temporary shadow of truth. This is confirmed in the Bhagavad-gita (param drstva nivartate).
