There are many other factors affecting our lives.
Kamm is only one of the five Niyamas.
The First Niyama (Utu Niyama) is the law of physical matter. It is the physical, inorganic order of existence. Seasonal changes, earthquakes, floods, gravity and heat are some of the many examples. It roughly embraces the laws of physics and chemistry.
The Second Niyama (Bija Niyama) is the law of living matter, the physical organic order, like cells and genes, whose laws are similar to the science of biology.
The Third Niyama (Kamma Niyama) is Karma. Karma is the activity of transforming energy through intention, speech and action. The result of this energy transformation is only considered wholesome or skillful if less suffering or no suffering is produced. Karma is the cause, and Vipaka (Pali) is the result. It is the principle of conditionality operative on the moral plane. This sequence of cause and consequence replaces a divine law giver. In Buddhism there is a moral law, but no lawgiver and no one to administer it. This Niyama pertains to the world of ethical responsibility.
The Fourth Niyama (Dhamma Niyama) is the Spiritual or transcendent. This principle of conditionality operates on the spiritual level. The natural phenomenon that occurs with the birth of a Buddha, and the reasons for Buddhist Practice are in this group. This Niyama has to do with the spiritual laws that govern ultimate reality.
The Fifth Niyama (Citta Niyama) is mind. This Niyama implies mental activity such as consciousness, perception, conception, etc. Mental phenomenon arises because of conditions; the mind is not an independent agent. This is like the science of psychology.
