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.
How this ancient wisdom applies to your daily life

This verse reveals the Supreme as the controller: the Supreme Lord dwells in the region of the heart of all beings (īśvaraḥ sarvabhūtānāṁ hṛddeśe 'rjuna tiṣṭhati), causing all beings to revolve as if mounted on a machine, by maya (bhrāmayan sarvabhūtāni yantrārūḍhāni 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. When you understand this, you realize: you don't need to think you are the controller. You can recognize that the Supreme is the real controller, and you should surrender to Him. This is the path: recognizing the Supreme as controller and surrendering to Him, rather than thinking you are the controller.

Do you think you are the controller of your actions? Are you making decisions as if you're in complete control? What would change if you understood that the Supreme Lord dwells in your heart and controls all beings, making them move like puppets on a machine through maya?
