Sleep
Abhavapratyayalambana Tamovrittir Nidra: The mind has the faculties of cognition - Pramana, misapprehension - Viparyaya and imagination - Vikalpa. It has a fourth capability too, which happens to all at the end of day time - sleep.
Sleep happens daily at night and sometimes during the day too, when there is an absence of any thoughts, notions or ideas. The mind holds on to this attitude of a state of no thoughts when it takes rest, along with the body.
Either, when it is the time to sleep at night, or when the body is tired with hard work and exhausted and also when the mind is bored, it slips from conscious activities of working, talking and thinking and settls down like a wave that rises high and falls back into the ocean. Every living creature is a similar wave of expression that falls back to a few hours of rest.
During this period of rest, the mind is submerged in the super-conscious self and wakes up in the morning or at any time, after sleep -refreshed and rejuvenated.
