The cause for gradation in devotion and religious practices lies in God’s own system of creation in consonance with the intrinsic nature and individuality of souls. The individual qualities are natural and eternal; so it is natural that there should be differences in the qualities of aspirants in God’s creation, which is based on a set of facts like intrinsic difference of souls.
Sri Krishna says: The four varnas have been created by Me based upon the proportions of the qualities – satva, rajas & tamas, and tendency for work. Know Me, the unchanging author of that fourfold system, and the one who is without a maker.
