Krishna moves to a deeper, more integrated level of sacrifice. He describes practitioners (cāpare) who take all the activities of their senses (sarvāṇīndriya-karmāṇi) as well as all the activities of their vital life force or breath (prāṇa-karmāṇi) and sacrifice them (juhvati) into a single, blazing location: the fire of the yoga of self-restraint (ātma-saṃyama-yogāgnau). Crucially, this fire must be illuminated and kindled by pure knowledge (jñāna-dīpite).
