The less intelligent jivas try to remain within this material world and are accordingly elevated and degraded in the various planetary systems. During the daytime of Brahma they exhibit their activities, and at the coming of Brahma's night they are annihilated. In the day they receive various bodies for material activities, and at night these bodies perish. The jivas (individual souls) remain compact in the body of Visnu and again and again are manifest at the arrival of Brahma's day. When Brahma's life is finally finished, they are all annihilated and remain unmanifest for millions and millions of years. Finally, when Brahma is born again in another millennium, they are again manifest. In this way the jivas are captivated by the material world. However, those intelligent beings who take to Krsna consciousness and chant Hare Krsna, Hare Rama in devotional service transfer themselves, even in this life, to the spiritual planet of Krsna and become eternally blissful there, not being subject to such rebirths.
