Prashna Upanishad 4.6
intermediate
स यदा तेजसाभिभूतो भवति। अत्रैष देवः स्वप्नान्न पश्यत्यथ तदैतस्मिञ्शरीरे एतत्सुखं भवति॥
sa yadā tejasābhibhūto bhavati | atraiṣa devaḥ svapnānna paśyatyatha tadaitasmiñśarīre etatsukhaṃ bhavati ||
""When one is overcome by light (deep sleep), then this god does not see dreams. Then in this body arises that happiness.""
What This Means:
In deep sleep, even dreams cease. The Self merges into its own light. This brings the profound happiness of deep sleep.
Going Deeper:
Deep sleep (sushupti) is blissful because the Self temporarily returns to its source, free from the disturbance of waking or dreaming.
How To Apply This:
The peace of deep sleep is a taste of your true nature. Meditation aims to access this while awake.
