One of the mainstays for a liberated life according to the Bhagavad Gita, is samatvam or equanimity. This is also called having sama darshanam or equity in vision, i.e. looking at everything as inherently the same, irrespective of whether it is good or bad, pleasure or pain, joy or sorrow and so on.
To live comfortably and mentally unblemished in the face of criticism, one must begin by eschewing praise. We cannot have the proverbial cake and eat it too. We want equanimity in hardship, but our pleasure receptors shoot through the roof in the slightest hint of praise and recognition.
How can we then practically be equanimous? When the boss says “Wow you’ve done amazing work here, you deserve this promotion!”, do we just scowl at him and walk away? Or do we say “No sir, it wasn’t me.” The boss is then likely to keep the promotion/bonus for himself 🙂
The way prescribed in the scriptures, is ‘surrender’. Surrender with faith, to the divine, or if that’s too abstract, then to the Guru. In Hindi, sur means head. So putting your head under the Guru or ishta devata, offering everything to him or her. Everything means all good and all bad without distinction. So grab that promotion by all means, but mentally prostrate and offer it to your deity of choice. This will keep us grounded, always. Difficult, but worth it.
