OM SRI SAI RAM
Perplexed by the seemingly inexplicable, apparent disparity that existed among humanity, a young truth-seeker approached the Buddha and questioned him regarding this intricate problem of inequality:
"What is the cause, what is the reason, O Lord," questioned he, "that we find amongst mankind the short-lived and long-lived, the healthy and the diseased, the ugly and beautiful, those lacking influence and the powerful, the poor and the rich, the low-born and the high-born, and the ignorant and the wise?"
The Buddha’s reply was:
"All living beings have actions (Karma) as their own, their inheritance, their congenital cause, their kinsman, their refuge. It is Karma that differentiates beings into low and high states."
He then explained the cause of such differences in accordance with the law of cause and effect.
Certainly we are born with hereditary characteristics. At the same time we possess certain innate abilities that science cannot adequately account for. To our parents we are indebted for the gross sperm and ovum that form the nucleus of this so-called being. They remain dormant within each parent until this potential germinal compound is vitalised by the karmic energy needed for the production of the foetus. Karma is therefore the indispensable conceptive cause of this being.
The accumulated karmic tendencies, inherited in the course of previous lives, at times play a far greater role than the hereditary parental cells and genes in the formation of both physical and mental characteristics.
Dealing with this problem of variation, the Atthasalini, being a commentary on the Abhidharma, states:
"Depending on this difference in Karma appears the differences in the birth of beings, high and low, base and exalted, happy and miserable. Depending on the difference in Karma appears the difference in the individual features of beings as beautiful and ugly, high-born or low born, well-built or deformed. Depending on the difference in Karma appears the difference in worldly conditions of beings, such as gain and loss, and disgrace, blame and praise, happiness and misery."
Thus, from a Buddhist point of view, our present mental, moral intellectual and temperamental differences are, for the most part, due to our own actions and tendencies, both past and present.
