Yoga Sutras of Patanjali · 3.43

बहिरकल्पिता वृत्तिर्महाविदेहा ततः प्रकाशावरणक्षयः॥४३॥

bahir akalpitā vṛttir mahāvidehā tataḥ prakāśa-āvaraṇa-kṣayaḥ

The great discarnate state — a real (not imagined) mental function existing outside the body — is achieved. By that, the covering of the inner light is destroyed.
