Our natural position as a living entity is that we have to serve something. Every living entity has to serve. That's our natural position. If something is wrong with my hand and I want to be cured, I don't grab onto some foodstuffs or some medicine, some herbs, and squeeze it with the hand and think that this hand is going to be cured. I take the medicine or the food through my mouth, and then it circulates through the digestive system and through the veins, and finally comes to the hand and can work its cure.
So the hand, unless it's serving its source, then it's useless. The servant must serve its master, or the part must serve the whole. And our relationship with God is the same. Just like the hand is made out of bile, blood and air, flesh and bone, as all the body is, so similarly we're made out of spirit—qualitatively the same as Kṛṣṇa, but quantitatively many millions of times less. Qualitatively the same; quantitatively different. Fragmental portion.
So if we fragmental portions, separated parts and parcels, can serve the source, or the whole, then we can be cured of this material disease which is rampant nowadays. And this is possible only by mercy. By mercy alone we can transcend this material existence and know that I am part and parcel of the Supreme, Kṛṣṇa, or God, and I can erase all of my karma and situate myself in pure consciousness. But this consciousness cannot be purified unless there is mercy. And in this age, 'Kali-yuga, as we know, mercy is diminished to being almost nonexistent. And 'Kali-yuga is just beginning.
