Yes. We all create the world we live. But at times conflict exists between our perception and the ultimate reality. Such as with mass hysteria, or psychosomatic delusion. What we believe can influence our body's physical reaction to a psychological response, only to a certain point.
What's normally thought of as karma is only a tendency, but can often seem to violate it. That's because karma is only one of five forces "controlling" our end results.
"Being created by an Almighty God who controls our destinies and predetermines our future, or being produced by an irresistible Karma that completely determines our fate and controls our life’s course, independent of any free action on our part, is essentially the same. The only difference lies in the two words God and Karma. One could easily be substituted for the other, because the ultimate operation of both forces would be identical.
Such a fatalistic doctrine is not the Buddhist law of Karma.
According to Buddhism, there are five orders or processes
(niyama) which operate in the physical and mental realms.
They are:
- Utu Niyama- physical inorganic order, e.g. seasonal phenomena of winds and rains. The unerring order of seasons, characteristic seasonal changes and events, causes of winds and rains, nature of heat, etc., all belong to this group.
- Bija Niyama - order of germs and seeds (physical organic order), e.g. rice produced from rice-seed, sugary taste from sugar-cane or honey, peculiar characteristics of certain fruits, etc. The scientific theory of cells and genes and the physical similarity of twins may be ascribed to this order.
- Karma Niyama - order of act and result, e.g., desirable and undesirable acts produce corresponding good and bad results. As surely as water seeks its own level so does Karma, given opportunity, produce its inevitable result, not in the form of a reward or punishment but as an innate sequence. This sequence of deed and effect is as natural and necessary as the way of the sun and the moon.
- Dhamma Niyama- order of the norm, e.g., the natural phenomena occurring at the advent of a Bodhisattva in his last birth. Gravitation and other similar laws of nature. The natural reason for being good and so forth, may be included in this group.
- Citta Niyama - order or mind or psychic law, e.g., processes of consciousness, arising and perishing of consciousness, constituents of consciousness, power of mind, etc., including telepathy, telaesthesia, retro-cognition, premonition, clairvoyance, clairaudience, thought-reading and such other psychic phenomena which are inexplicable to modern science."
