Soul, Ego and Path. The formula of life is love

We are all students in school called "Life". We come to get wisdom lessons and benefit from their mistakes. Between the entrance and exit, we have the opportunity to undergo training, successfully or not, having mastered the three main steps: acceptance, love and awareness. The ultimate goal of our land visit is the evolution of consciousness or awareness that the inner harmony is not achieved by the external victories over the enemies of the reality around us. Even crushing with the success of all rivals, we are not insured against the meeting with our own internal enemies. And only having fun and undivided power over them, we can count on absolute invulnerability from external influences. Is this the state that Buddhists call Nirvana, and Christians are the descent of the Holy Spirit or grace?
