Vedantasara - Verse 92
Sanskrit
अस्यैषा समष्टिः स्थूलप्रपञ्चापेक्षया सूक्ष्मत्वात्सूक्ष्मशरीरं विज्ञानमयादिकोशत्रयं जाग्रद्वासनामयत्वात्स्वप्नोऽतएव स्थूलप्रपञ्चलयस्थानमिति चोच्यते
Swami Nikhilananda's Translation
This aggregate made up of three sheaths such as Vijnanamayakosa etc., (which forms the limiting adjunct) of Hiranyagarbha is called the subtle body as it is finer than the gross universe. It is also called the dream state, as it consists of the impressions of the waking state; and for that very reason it is known as the merging place for the gross universe.
