Asnāviram means in the body of God there are no veins, and so therefore apāpa-viddham. Veins, as soon as you have got this veins, that is material body. The body is maintained under certain material condition. You eat, and this eating substance transformed into secretion, then through the veins this comes to the heart, and heart it becomes red, corpuscle, the blood, the blood is diffused. Therefore there are so many channels, veins. And these things are pushed on with air, and if there is shortage of air circulation, the man becomes paralyzed. This is scientific.
So these things are required for the material body, not for the spiritual body. In spiritual body, asnāviram, there is no vein. Therefore one who misunderstands Kṛṣṇa as having a material body, he has been described in the Bhagavad-gītā as mūḍhā. Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam (BG 9.11). He has no veins. There is no difference between His body and soul. We have got difference with our body and soul; therefore this existence with this material body is not śuddha, is not pure.
