Experiencing a life full of different events, which can be harmful at times, can be demanding and make life a difficult journey of ups and downs. We also realize that we can withstand and tolerate situations, and not only a few people but all of us try to some extent or the other. Of course, some of us fail entirely, also.
There is no substitute for correct thinking when a difficult situation is in front of you. You think negatively but act according to the spiritual knowledge you have read. That will not make you successful in overcoming the situation. Inner habits of creating thoughts of fear, pessimism, hopelessness and impatience will not reduce, although we may temporarily feel positive based on what we have read or learnt.
Inner habits are intense and have been inside the inner spiritual being or soul since many births. Each time we have performed an adverse action or created a negative thought, a sanskara was made based on that thought, word or action. This is the cycle of repetition. And this cycle keeps having a more powerful negative influence on us the more it is repeated.
We must get out of this vicious cycle and convert these constant negative thoughts into positive ones. We have several goals, but the first goal should be to eliminate negative beliefs and replace them with positive ones. This takes a calm mind with determination. We should never think we can't be positive as we still have those qualities in us.
