Vedic knowledge is not imparted by such defective living entities. It was imparted unto the heart of Brahmā, the first created living being, and Brahmā in his turn disseminated this knowledge to his sons and disciples, as he originally received it from the Lord. The Lord is pūrṇam, all-perfect, and there is no possibility of His becoming subjected to the laws of material nature. One should therefore be intelligent enough to know that the Lord is the only proprietor of everything in the universe and that He is the original creator, the creator of Brahmā. In the Eleventh Chapter the Lord is addressed as prapitāmaha (BG 11.39) because Brahmā is addressed as pitāmaha, the grandfather, and He is the creator of the grandfather. So no one should claim to be the proprietor of anything; one should accept only things which are set aside for him by the Lord as his quota for his maintenance.
There are many examples given of how we are to utilize those things which are set aside for us by the Lord. This is also explained in Bhagavad-gītā. In the beginning, Arjuna decided that he should not fight in the Battle of Kurukṣetra. This was his own decision. Arjuna told the Lord that it was not possible for him to enjoy the kingdom after killing his own kinsmen. This decision was based on the body because he was thinking that the body was himself and that his bodily relations or expansions were his brothers, nephews, brothers-in-law, grandfathers and so on. Therefore he wanted to satisfy his bodily demands. Bhagavad-gītā was spoken by the Lord just to change this view, and at the end Arjuna decides to fight under the directions of the Lord when he says, kariṣye vacanaṁ tava (BG 18.73): "I shall act according to Your word."
