श्लोकवार्तिक - दोषदृष्टिपरं मनः

न चात्रातीव कर्तव्यं दोषदृष्टिपरं मनः ।
दोषो ह्यविद्यमानोऽपि तच्चित्तानां प्रकाशते ॥

- श्लोकवार्तिक

One must not pay too much attention to negative feelings surrounding one self. If one concentrates too much on them, he will see negativity even when none such exist.
