Dwell not on the faults and shortcomings of others; instead, seek clarity about your own.
Gautama BuddhaCut down the forest, not just a tree. Out of the forest of desire springs danger. By cutting down both the forest of desire and the brushwood of longing, be rid of the forest, bhikkhus.
Gautama BuddhaDo not dwell in the past, do not dream of the future, concentrate the mind on the present moment.
Gautama Buddha
