Santokh
Santokh, or contentment, is freedom "from ambition, envy, greed and jealousy. Without contentment, it is impossible to acquire peace of mind."
Practice truth, contentment and kindness; this is the most excellent way of life. One who is so blessed by the Formless Lord God renounces selfishness, and becomes the dust of all.
— Guru Granth Sahib, ang 51
