The human mind in animal consciousness is competitive and self preservation is its prime motive - where self is assumed to be body. So wherever one goes, one starts seeing others as competitors, openly or covertly. For example - when one moves to a new locality, one starts competing with one's neighbors. The neighbors also "size up" the newcomers. It is interesting that prior to moving there, both had no such thoughts about one another!
The human mind in human consciousness is collaborative and justice (nyaya) is its prime motive. Wherever such human being goes, he sees others as fellow human beings, seeking collaboration by becoming complementary for the sake of justice. This collaboration requires valuation (mulyankan) of oneself and that of other person. This valuation is absolute, based on understanding of reality, which is different from the "sizing up" of animal consciousness, which always has the flaw of over-valuation, under-valuation or un-valuation. From the stand-point of human consciousness, competition is meaningless, therefore unnecessary. Where competition is, justice is not. Also, where justice is, competition is not. Competition is with comparison - less versus more, which has to be associated with something material, for the conscious aspects are immeasurable. Unless conscious aspect is understood, it is not possible to overcome the competitive mindset and accomplish justice in one's living.
Competition in animal consciousness at large scale divides human population into "winners" and "losers". Competition grades and fragments people - for example: excellent, good, average, poor, very poor. It may give better sounding names for the lower rungs, but that doesn't change the fact that lower rungs are "losers" in this scheme of things. The "winners" would be very few, and it would be considered "normal" to have most people in the "average" range. There are whole lot of statistical analyses to establish the truth of this! Haven't you heard of the "bell curve"? It's clear that the "losers" of animal consciousness would not lead a happy life. What about "winners"? Would these winners live happily? The richer are not necessarily the happier lot. Happiness is quite the essential point for human living - be it animal consciousness or human consciousness. In animal consciousness, one seeks (in vain, of course!) "happiness" as result of the effect (as a sensation in body and feeling thereby) of some event. In human consciousness, one is rooted in happiness, as realization in knowledge, and all thoughts, feelings and actions remain in "natural control" (niyantran). The "happiness" of animal consciousness is not of lasting kind. It is important to note here, that one doesn't seek happiness as outcome of one's actions in human consciousness. Happiness is one's state of being. Human consciousness and animal consciousness are two planes of being in human existence. A human being transcends (sankraman) to human consciousness from animal consciousness upon achieving realization (anubhav) in knowledge of existence.
