According to Osho, ‘yogasthaḥ kuru karmāṇi’ means: first abide in meditative awareness—the witnessing center—then act. Rooted in inner silence, drop attachment to results and the ego of doership; let action flow spontaneously. Success and failure are equal tastes when you act from this center, turning work into play, duty into love, and karma into a path to freedom rather than bondage.
Be calm and aware inside first, then do your work without clinging to winning or losing.
