Bhagwad Gita
Chapter 18, Verse 8
दुःखमित्येव यत्कर्म कायक्लेशभयात्त्यजेत्।स कृत्वा राजसं त्यागं नैव त्यागफलं लभेत्।।18.8।।
Anyone who gives up their necessary work because they find it hard or feel scared is acting out of a passionate attitude. This kind of giving up does not help them move towards true renunciation.
