Bhagavad Gita · Chapter 2: The Path of Understanding
Bhagavad Gita 2.37
हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम् ।
तस्मादुत्तिष्ठ कौन्तेय युद्धाय कृतनिश्चयः ॥
hato vā prāpsyasi svargaṃ jitvā vā bhokṣyase mahīm | tasmāduttiṣṭha kaunteya yuddhāya kṛtaniścayaḥ ||
If you are killed, you will gain heaven; if you win, you will enjoy the earth. So stand up, Arjuna, resolved to fight.
Modern context
Arjuna had said he did not know whether winning or losing was better. Krishna answers that when you are doing what is right, both outcomes are acceptable. Fear of failure loosens once we see that an honest effort is worthwhile whichever way it ends. What paralyses us is the belief that only one result can be borne.
