Bhagavad Gita 6.1

श्रीभगवानुवाच ।

अनाश्रित: कर्मफलं कार्यं कर्म करोति य: ।
स सन्न्यासी च योगी च न निरग्निर्न चाक्रिय:  ॥

śrī bhagavān-uvāca

anāśrita: karma-phalaṃ kāryaṃ karma karoti ya:
sa sannyāsī ca yogī ca na niragnir-na cākriya: – 1 

Lord Krishna said: Whoever does whatever is needed from time to time, without depending on the mind’s sukha-du:kha creations (karma-phala), verily is a sannyāsin and yogi – not one abandoning rituals or activities.
