All glories to Srila Prabhupad.
Knowledge is the most precious possession of any human being. Among all the types of knowledges, the spiritual knowledge is the supreme as per Bhagbat Gita. So, despite one's level of any material knowledge, what is most important for any human is his spiritual knowledge. Because this is related to his spirit soul, which is his real & shuttle existence. Therefore, depending upon one's level of spiritual knowledge, he is bound to be there, where he is, at present.
