Krishna informs us that beyond this material world is a spirit | The Bliss Of Krishna Consciousness
Krishna informs us that beyond this material world is a spiritual sky, which is filled with innumerable planets. That sky is far, far greater than material space, which constitutes only one fourth of the entire creation. Similarly, the living entities within the material world are but a small portion of the living entities throughout the creation.
This material world is compared to a prison, and just as prisoners represent only a small percentage of the total population, so the living entities within the material world constitute but a fragmental portion of all living entities.
Those who have revolted against God-who are criminal-are placed in this material world. Sometimes criminals say that they don't care for the government, but nonetheless they are arrested and punished. Similarly, living entities who declare their defiance of God are placed in the material world.
Originally the living entities are all part and parcel of God and are related to Him just as sons are related to their father. Christians also consider God the supreme father. Christians go to church and pray, "Our Father, who art in heaven." The conception of God as father is also in the Bhagavad-gita [14.4] :-
sarva-yoniṣu kaunteya
mūrtayaḥ sambhavanti yāḥ
tāsāṁ brahma mahad yonir
ahaṁ bīja-pradaḥ pitā
"It should be understood that all the species of life, O son of Kunti, are made possible by birth in this material nature, and that I am the seed giving father."
