SB 2.6.29, Translation and Purport

My dear son, thereafter your nine brothers, who are the masters of living creatures, performed the sacrifice with proper rituals to satisfy both the manifested and nonmanifested personalities.

The manifested personalities are the demigods like the ruler of the heavenly kingdom, Indra, and his associates; and the nonmanifested personality is the Lord Himself. The manifested personalities are mundane controllers of the material affairs, whereas the nonmanifested Personality of Godhead is transcendental, beyond the range of the material atmosphere. In this age of Kali the manifested demigods are also not to be seen, for space travel has completely stopped. So both the powerful demigods and the Supreme Personality of Godhead are nonmanifested to the covered eyes of the modern man. Modern men want to see everything with their eyes, although they are not sufficiently qualified. Consequently, they disbelieve in the existence of the demigods or of the Supreme God. They should see through the pages of authentic scriptures and should not simply believe their unqualified eyes. Even in these days, God can also be seen by qualified eyes tinged with the ointment of love of God.
