What is positive thinking really?

Positive thinking is not avoiding every negative thing. Real positive thinking is if you think that negative things will help you in your development. When negative thoughts appear, you go in the wrong direction, you shouldn't carry on your train of thought in that way. With continuous practise you can change your negative thinking to positive thinking.

A person doesn't distinguish positive or negative feelings at a high level of individual development. Then you will concentrate only on health, harmony, and joy because these will become part of your life. In a state of balance there is no positive and negative, no good and bad, there are just things the way they are. Judgements, the distinctions of good and bad are the achievement of the unbalanced state. 

You should always pay regard to your surroundings: because with negative thoughts you can make others sick around you, while with the positive ones you can heal! Positive thinking is the best medicine for every problem: it is free, it is at your disposal in unlimited amounts and it has no harmful side effects.
