kāryaḿ karma karoti yaḥ
sa sannyāsī ca yogī ca
na niragnir na cākriyaḥ
Translation of Bhagavad Gita 6.1
The Supreme Personality of Godhead said: One who is unattached to the fruits of his work and who works as he is obligated is in the renounced order of life, and he is the true mystic, not he who lights no fire and performs no duty.
