The tamasic knowledge is a small and narrow way of looking at things which has no eye for the real nature of the world; it clings to one movement or one routine as if it were the whole (without foresight or comprehending intelligence).
Gītā 18·22The tamasic ignorant knowledge is a small and narrow, a lazy or dully obstinate way of looking at things which has no eye for the real nature of the world or of the thing done or its field or the act or its conditions. The tamasic mind does not look for real cause and effect, but absorbs itself in one movement or one routine with an obstinate attachment to it, can see nothing but the little section of personal activity before its eyes and does not know in fact what it is doing but blindly lets natural impulsion work out through its deed results of which it has no conception, foresight or comprehending intelligence.
