 Taoist propriety and ethics may vary depending on the particular school , but in general they tend to emphasize wu @-@ wei ( action through non @-@ action ) , " naturalness " , simplicity , spontaneity , and the Three Treasures : jing ( sperm / ovary energy , or the essence of the physical body ) , qi ( energy , including the thoughts and emotions ) , and <unk> ( spirit or spiritual power ) .
