Why are the waker and the dreamer said to be made of seven parts in the Mandukya Upanishad?

[Dr. Nikhil asked: Padanamaskarams Swamiji, I offer the attached question at Your divine lotus feet. Why in the Māṇḍūkya Upanishad are the waker (viśva) and the dreamer (taijasa) said to be made of seven parts (saptāṅga), whereas the Prājña is said to be single and undifferentiated (ekībhūta)? Your servant, Nikhil]

Swami replied:- The waker and dreamer refer to the ordinary individual soul because both these waking and dreaming states are common to incarnation and ordinary souls. In the case of deep sleep represented by the Praajna, this state is for incarnation only in which the soul is the leftover God. In this state, in the case of ordinary human beings, the soul or individual soul is totally absent. The individual soul is always a part of the creation and can have the composite nature having several parts. God is always one only without any second item (Ekamevādvitīyaṃ Brahma, Neha nānāsti kiñcana– Veda).
