“The living entities, as separate parts and parcels of the Supreme, have a purpose to fulfill. Having forgotten that purpose, since time immemorial they are situated in different bodies, as men, animals, demigods, etc. Such bodily differences arise from forgetfulness of the transcendental service of the Lord. But when one is engaged in transcendental service through Krishna consciousness, one becomes at once liberated from this illusion.” (Shrila Prabhupada, Bhagavad-gita, 4.35 Purport)
