You are all-pervading within your body; I know the pains and pleasures of my body; you know the pains and pleasures of your body. So all-pervading means within this body. If I pinch anywhere, I'll feel pain, you'll not feel pain. Therefore, you are not all-pervading, I am not all-pervading. But Krsna is all-pervading. When I feel pain, Krsna knows it. Vedaham samatitani [BG 7.26]. "I know everything." That is Krsna. Try to understand distinction between Krsna and us. He's all-pervading, but He's nitya, ever-existing. We are also ever-existing. Nityo nityanam cetanas cetananam (Katha Upanisad 2.2.13). We have got knowledge, Krsna has got knowledge. But we have got limited knowledge. Krsna has got unlimited knowledge. That is the difference.
