In religious activities, ordinary dealings and personal survival one cannot avoid value judgements. Morality and religion are perennial necessities in civilized society; therefore distinctions between purity and impurity, piety and impiety, morality and immorality must somehow be ascertained. Similarly, in our ordinary, worldly activities we distinguish between palatable and tasteless food, good and bad business, high-class and low-class residences, good and bad friends, and so forth. And to insure our physical health and survival, we must constantly distinguish between what is safe and unsafe, healthy and unhealthy, profitable and unprofitable. Even a learned person must constantly distinguish between good and bad within the material world, but at the same time he must understand the transcendental position of Krishna consciousness. Despite one's careful calculation of that which is materially healthy and unhealthy, the physical body will collapse and die. Despite careful scrutiny of the socially favorable and unfavorable, one's entire social milieu will vanish with the passing of time. In the same way, great religions arise and disappear in the course of history. Thus mere religiosity, social and financial expertise or physical fitness cannot award the actual perfection of life. There is a transcendental good beyond the relative good of the material world. Any sane person accepts the practical and immediate necessity of material discrimination; yet one must come ultimately to the transcendental stage of Krishna consciousness, where life is eternal, full of bliss and knowledge. Lord Krishna, in His elaborate teachings to Sri Uddhava, is gradually clarifying the transcendental position of Krishna consciousness beyond the endless variety of material good and evil.
