शोकहर्षौ तथायासः सर्वं स्नेहात्प्रवर्तते

忧悲与欢喜,以及劳顿与辛苦——一切皆由执著之爱而起。
Lomaharṣaṇa (Sūta)

Emotional swings and exhaustion trace back to attachment; steadiness comes from loosening possessiveness and craving.
None is mentioned; it is a universal teaching.
No; it is a doctrinal statement about the mind.
