One has to become purified by freeing himself from all designations. This is the first step. We are now under different designations. Every one of us is thinking that "I am this body, and because I am this body and this body is produced under certain condition, in a certain family, by certain father and mother, in a certain society, certain country, certain land, therefore I have got, you have got so many designations." But we have to become first of all free from the designations. That is the first qualification for understanding the science of God.
