Bhagavad Gita · 5.11

कायेन मनसा बुद्ध्या केवलैरिन्द्रियैरपि।योगिनः कर्म कुर्वन्ति सङ्गं त्यक्त्वात्मशुद्धये॥

kāyena manasā buddhyā kevalair indriyair api yoginaḥ karma kurvanti saṅgaṁ tyaktvātma-śhuddhaye

Yogis perform actions with the body, mind, intellect, and even the senses alone, abandoning attachment, for the purpose of self-purification.
