Chapter 16Sleep · Sleep during the Day
Book 8. Part Three: Sadhana on the Physical, Subconscient · Section Two: Food, Sleep, Dreams and Sex

* According to the old Ayurvedic shastra “sleep by day impairs the vitality”; but there are conditions in which the rule may not apply. It is however true that these [sexual] dreams do easily occur during sleep by day and the dreams themselves come in a state of deep subconscient relaxation, tamasic inertia when the system can be touched by any subconscient suggestion or influence.
