When Sakyamuni Buddha was born, he said, "Heaven is the only one in the world." Please explain the meaning of this sentence.

Looking at all religions in the world, except Buddhism, there is no religious leader who does not pretend to be superman. This god can call the wind and rain, turn stone into gold; He dominates the fate of mankind, and it manipulates the life and death of all things. Only by falling down before him, praising and eulogizing, and attributing all the success and glory to Almighty God, can mankind go to heaven only by believing in him. Those who oppose him will only fall into hell, and there is no room for defense and appeal.

The first sentence of Sakyamuni, the founder of Buddhism, when he came to the world was:' Heaven and the world are unique.' What readers should pay attention to here is that the word "I" of "I am the only one" refers not only to Sakyamuni himself, but to everyone in all mankind. The correct interpretation of this sentence should be: man is indomitable in the universe, and everyone is his own master and decides his own destiny without obeying anyone or any god beyond him.
