Simple explanation of the law of karma: Some people are born into wealthy families, where they receive a good education and have all facilities in life. Others are born in very poor families and have to struggle for existence since their early days. Some are born with very health bodies, others are born with a weak constitution or some incurable disease. Some are born very intelligent, others not so much. Some are beautiful, others ugly, some are born with physical defects, others are killed in the womb, without the opportunity of being born at all. Opportunities are not the same. Some start life with a huge advantage and others in the opposite situation. How can this be explained?
