The Yoga of Liberation by Renunciation

Krishna reveals the Supreme as the controller. 'Īśvaraḥ sarvabhūtānāṁ hṛddeśe 'rjuna tiṣṭhati'—the Supreme Lord (īśvaraḥ) dwells (tiṣṭhati) in the region of the heart (hṛd-deśe) of all beings (sarva-bhūtānām), O Arjuna (arjuna). 'Bhrāmayan sarvabhūtāni yantrārūḍhāni māyayā'—causing to revolve (bhrāmayan) all beings (sarva-bhūtāni) as if mounted on a machine (yantra-ārūḍhāni), by maya (māyayā). This is the key teaching: the Supreme Lord is present in the heart of every being, and He controls all beings, making them move like puppets on a machine, through maya (His divine power). This reveals that you are not the ultimate controller—the Supreme is the controller, and you are being moved by His will through maya. Understanding this helps you recognize that you should surrender to the Supreme, who is the real controller.
