The cliché, “What goes around comes around,” is the American definition of karma.
Karma, from the root kri, “to do,” is the means by which you become the architect of your own destiny. The word karma literally means act, but it implies the complete cycle of cause and its effects. According to the law of karma, every human action, whether in thought, word or deed, inevitably leads to results or consequences, positive or negative, depending on the quality of the action.
Karma deals with causality. A specific action leads to a specific result. A positive act will lead to a positive result, thus the experience of positive events, whether in this life or in future ones. On the other hand, negative acts will inevitably sooner or later lead to suffering. This is the Law of Cause and Effect itself, because the result will inevitably correspond to the nature of the cause. For example, if you plant a seed, a certain type of plant will grow from it. From a bean seed a bean plant will grow; an apple tree will grow from an apple seed and not another species. The effects of a deed, word or thought are sometimes immediate but in some cases many days, months, years or lifetimes go by until the precise moment arrives. Buddha said, “Our good and bad deeds continually follow us like shadows.”
You must remember that thoughts and words are also considered karma. Wishing is also a type of action, so you must be very aware of your bad desires in order to get rid of them immediately. Negative emotions such as anger, hatred, envy, selfishness, jealousy, etc. they are also bad actions that lead to negative reactions–suffering, so we must keep in mind that each of our physical, emotional, verbal or mental actions has its repercussions throughout the Universe.
Negative thoughts or disturbing emotions can arise within us every day. This is not a sin, but if you allow those harmful emotions to remain within you, strengthening them through bad actions, bad thoughts and wicked words, then you will be creating negative karma. Your duty is to get rid of those silly and pointless negative thoughts and emotions as soon as possible. Christ, Buddha, Mohammed and other great souls were not exempt from experiencing bad thoughts, fear, anger, sadness, hatred, selfishness or any other type of negative emotion, they worked to hastily eradicate these tremendous obstacles in their evolutionary process.
You must stop your negative thoughts and emotions so that you can prevent negative karma from accumulating. You generate about 60,000 thoughts every day, so it is very important to train your mind to constantly generate positive thoughts that lead to positive words and actions.
Not only our actions, but also our omissions become our destiny. Things that we had to do, but didn’t do, trigger reactions that can become events of great concern. For example, my grandmother was very sick on Sunday, but I decided not to visit her that day because she preferred to go to the movies. Days went by and after three days she died, so I didn’t visit her. This action will trigger adverse reactions in my destiny, since it was my moral duty to go through her house to give her optimism and spiritual strength through affectionate actions and words of love towards her.
None of us like to suffer and our biggest mistake lies in thinking that we need to overcome difficult periods as quickly as possible, not realizing that this experience purifies our soul and gives us the opportunity to evolve at a higher rate. You need to accept suffering with faith, dedication, resignation and humility, praying to the Almighty for the purification of your soul and for your spiritual liberation. You must remember that the hellish moments are preparing you to give birth to something invaluable, spiritual evolution. You need to welcome all circumstances as part of your treasure trove of opportunity. Many in your life can magnetically pull you into the valleys of pain to pull you out of your old comfortable ruts and onto new paths of thought. In every difficulty lies the golden seed of uplifting spiritual change. You gain inner strength and spiritual evolution from overcoming difficulties.
You have resolved millions of different karmas from many past lives, and in a single day you create a lot of new karma through your thoughts, words and actions. Sometimes it’s positive, sometimes it’s negative, but unfortunately, it’s usually negative because you, as a human being, constantly have disturbing thoughts and emotions that rarely result in something positive, but rather in wrong actions. You can act with love towards your family, this is your Dharma duty, consequently you will reap the love of your relatives and evolve spiritually. If you want love, give unconditional love.
If you create negative karmas, actions, killing, stealing, lying, criticizing, etc., then you will reap terrible results like illnesses, calamities, hardships or any kind of suffering. The greater the sacrifice and the goodness of the action, the greater the fruit you will receive. Similarly, a mean or negative action, which inflicts pain and suffering on other beings, will bring equivalent results to the one who performs it. For every action, word and thought there will be a reaction, a fruit, of the same nature and degree. The Law of Cause and Effect is inviolable and no one escapes it. This law operates in every situation, in every place, at any time within the created Universe, on every level of creation.
