Bhagavad Gita 2.71
Peace comes to one who moves without "mine" and without ego
विहाय कामान्यः सर्वान्पुमांश्चरति निःस्पृहः। निर्ममो निरहंकारः स शान्तिमधिगच्छति॥
That person attains peace who, abandoning all desires, moves about without longing, without the sense of "mine" and without egoism.
What this verse points to
The two words the verse singles out are nirmama, without "mine," and nirahankara, without "I-making." Not without possessions and not without a functioning personality — without the constant background labour of claiming things and defending a self.
Most tiredness at the end of a day is that labour rather than the work itself. The verse suggests that peace is what is left over when you stop paying that particular tax.
Sit with it
Count how many times in one sit a thought arrives with "my" or "I" fastened to it. No need to fix anything — the counting is the practice.
About the Bhagavad Gita
The Bhagavad Gita is a 700-verse dialogue set on the battlefield of Kurukshetra, in which Krishna counsels the warrior Arjuna at the moment he refuses to fight. Across eighteen chapters it draws together the paths of action, devotion, and knowledge into a single teaching on how to act without being bound by action. It sits inside the Bhishma Parva of the Mahabharata and has been the most widely commented-upon text in the Vedantic tradition, from Shankara onward.
