“A pure soul is the eternal servant of God as His fragmental part and parcel. He comes into contact with maya (illusion) due to the desire to lord it over maya, and that is the cause of his many sufferings. As long as he is in contact with matter, he has to execute work in terms of material necessities. Krishna consciousness, however, brings one into spiritual life even while one is within the jurisdiction of matter, for it is an arousing of spiritual existence by practice in the material world.” (Shrila Prabhupada, Bhagavad-gita, 5.29 Purport)
