Meditations by Marcus Aurelius Book 8 Page 31

But if it be somewhat that is amiss in thine own disposition, that doth grieve thee, mayest thou not rectify thy moral tenets and opinions. But if it grieve thee, that thou doest not perform that which seemeth unto thee right and just, why doest not thou choose rather to perform it than to grieve? But somewhat that is stronger than thyself doth hinder thee. Let it not grieve thee then, if it be not thy fault that the thing is not performed. ‘Yea but it is a thing of that nature, as that thy life is not worth the while, except it may be performed.

’ If it be so, upon condition that thou be kindly and lovingly disposed towards all men, thou mayest be gone. For even then, as much as at any time, art thou in a very good estate of performance, when thou doest die in charity with those, that are an obstacle unto thy performance.
