The quote "Life is a series of natural and spontaneous changes. Don't resist them - that only creates sorrow. Let reality be reality. Let things flow naturally forward in whatever way they like." is likely from which of the following philosophers?

Lao Tzu

More in details:

Lao Tzu was a mystic philosopher of ancient China, best known as the author of the Tao Te Ching. His association with the Tao Te Ching has led him to be traditionally considered the founder of Taoism. He is also revered as a deity in most religious forms of the Taoist religion, which often refers to Laozi as Taishang Laojun, or "One of the Three Pure Ones". Laozi translated literally from Chinese means "old master" or "old one", and is generally considered honorific.
