People with different languages, races, beliefs, customs, occupations, and educations were killed in Nice because they were accused of holding a celebration, being happy and full of hope. The mentioned differences gathered together only for celebration and being happy. No one asked the other about his/her religion or, even, his/her motivation to be there. Pleasure and energy connects the people and makes it easy and, even, more beautiful to be together. Is there anything more lovely than smile, excite and emotion in the world? So why do some people- I emphasize people - know happy as a crime, a crime for which they should be killed? I do not know how the God and the religion emphasizing on human equality ignore such intellectual vacuum in its theoretical principles such that some people abuse of it and commit a crime. In history, human happiness and cheerfulness were repeatedly infringed and were criticized and threatened by different religions.Why is it not possible to be a Muslim and live happily? Why is it not possible to respect others’ happiness and not condemn the songs to be silent and the hopes and their effect on human goodness and felicity due to our inability to perceive them? Why the words of God emphasizing on His mercifulness and generosity in daylong prayers are misinterpreted to this extend? It is the time when the 21st century man to release from any religious, political and philosophical deductions, thoughts, and beliefs; listen to song of nature, listen to God, to oneness, and unanimity; respect emotions, cheerfulness, and stimulation; lessen his rationality and logic and add his happiness; welcome others laugh, kiss, and twinkling without any interpretation; live the life entirely with the sole aim of beautifulness and happiness of the world; leave a world, family, and offspring full of song and hope. We should release from all I know and, with a free mind and a sensational soul, accept the life, existence, human, and nature as they are.for more information please visit: https: //alikhiabanian.wixsite.com/arti
