Mono no aware (物の哀れ), 'the pathos of things', and also translated as 'an empathy toward things', or 'a sensitivity to ephemera', is a Japanese idiom for the awareness of impermanence (無常, mujō), or transience of things, and both a transient gentle sadness at their passing as well as a longer, deeper gentle sadness about this state being the reality of life.
I believe this name suites perfectly for a place where people can come to prevent anxiety and depression, often found in big cities. This pavilion will become a refuge from the fast pace of life in big cities. Art and nature help it better than anything. Following spaces can help in reducing anxiety: a fishpond, creative studios located on the first floor; multimedia partitions (second floor); as well as a rock garden, where you can learn the art of rock balancing any time of the year.
