Bhagavad Gita 2.47

Your claim is to action alone, never to its fruits. Do not make the fruit the motive, and do not cling to inaction.

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन ।
मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥

karmany evadhikaras te ma phalesu kadacana |
ma karma-phala-hetur bhur ma te sango 'stv akarmani ||

Your claim is to action alone, never to its fruits. Do not make the fruit the motive, and do not cling to inaction.

When treating a mental health condition with medication, this verse becomes a strict, life-saving clinical rule. Your only responsibility is the action itself: swallowing the prescribed dose at the right time. You cannot control the "fruits"—you cannot force the medicine to magically work on the very first day, and you should not wait for a perfect mood before you decide to take your pill. Furthermore, "do not cling to inaction." If you feel slightly better after a single week, do not let that temporary "fruit" trick you into suddenly stopping your medication. Quitting a psychiatric medicine abruptly because you feel fine is dangerous and often causes a relapse. Do the simple daily action, take the prescribed dose, and let the healing process unfold on its proper clinical timeline.
