Kṛṣṇa begins the chapter on Dhyāna-yoga by refining the definition of a spiritualist. He says that one who performs their required duty without being attached to the results is the real ‘Sannyāsī’ and the real ‘Yogī’. He is not a yogī who simply stops working or stops performing family rituals. In ancient times, a sannyāsī would symbolically stop cooking (lighting fires) and retire from social duties. Kṛṣṇa clarifies that this physical act is not the essence of renunciation. A person can be a monk in a cave and still be attached to his own reputation, while a person in the world can be a true renunciant if his heart is unattached to profit. True spirituality is defined by ‘Anāśritaḥ’—not taking shelter of the results. It is about the quality of the inner life, not the absence of the outer life. Kṛṣṇa is telling Arjuna that he can be a warrior on the outside and a perfect monk on the inside if he simply lets go of the selfish motive for his actions.
