योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनंजय | सिद्ध्यसिद्ध्योः समो भूत्वा समत्वं योग उच्यते ||
Yogasthah kuru karmani
Perform your duties with balance, abandoning attachment, and remain equal in success and failure. This equanimity is called Yoga.
Modern Application: Balance is the essence of mastery.
Deep Wisdom: Krishna defines Yoga as mental balance — not just physical practice.
