This world is nothing more than one large school for the maturation of the souls that inhabit it. Sin, as we have been taught by the religions of this world, in fact does not exist. Instead of thinking of our transgression as sins, it would spiritually be more correct to call them mistakes.
I mean no insult to my fundamentalist readers, but my words are based on the immortality of soul, karma, and reincarnation. The notion that each of us is a body, that owns a soul; and has but one lifetime to determine whether we go to heaven or hell, is incorrect, and propagated by the religions of the world, in order to control the masses. The truth is that we ARE soul, and we take on various bodies, from lifetime to lifetime, in order to gain the experiences necessary in order to earn knowledge of our divinity.
These are not easy lessons to learn, and for most of us, we have spent multiple lifetimes in order to learn just one of the lessons. We learn through the accumulation of karma. Karma from the view point of eternity is not punishment, but rather a chance to realize past mistakes, and to learn from them. For example, say you as soul, have been working on overcoming prejudice. In a past lifetime, you were prejudiced against black people, and cruel to them. Chances are, in your next lifetime you will be a black man, under going what you did to others previously. As you can see, learning is a slow arduous journey for each individual soul.
Each one of us is here because we still have lessons to master. We are constantly being tested to assess our progress. Sometimes we pass the test and move on to something else, other times we fail. Failing a test is something we all do quite a bit, because none of us are perfect. If we were perfect, we would not be here, unless it was as a teacher for others. When we fail a test, we go through the karma involved, and then get retested.
So if you make a transgression, don’t regret it, and don’t fuss about it. You will be retested again soon.
Learn from everything, regret nothing.
