Grain reserves are ok if we lived in the 16th century, but what knowledge can they offer today? The world evolves, life gets harder and harder for an average person, but this is just the nature's way to produce change. I would not want to live many boring lives as a lama. I understand the end goal as stopping the wheel of samsara. In fact, I think we are living through the end of times, I would really not like to be reborn here.
