Bhagwad Gita
Chapter 18, Verse 54
ब्रह्मभूतः प्रसन्नात्मा न शोचति न काङ्क्षति।समः सर्वेषु भूतेषु मद्भक्तिं लभते पराम्।।18.54।।
One who is truly connected to the Supreme Spirit understands and experiences inner peace. Such a person does not feel sadness or a strong desire for anything. They treat all beings equally and, in this state, they achieve a deep connection and service to Me.
