The Truth is not Arbitrary or a Matter of Opinion, but can be Investigated, and Those who Earnestly Search for the Truth will Find It. The Truth is Hidden to the Blind, but he who has the Mental Eye Sees the Truth.
Gautama BuddhaDo not speak harshly to any one; those who are spoken to will answer thee in the same way. Angry speech is painful: blows for blows will touch thee.
Gautama Buddha
