Topic#1 : Meditation and Sleep
For most of the people, doing meditation is a bit challenging, not able to remain clam and stable for even 5 miutes and question comes to many, can I meditate during sleep. Now meditation requires a degree of awareness and intention (even during deep meditation) while sleep is a state where awareness fades.
Seep can be considered as physical + brain recovery
During Sleep 1) The brain clears metabolic waste 2) Memory gets Consolidated 3) Body repairs tissues
Meditation can be considered as active inner conditioning
During Meditation 1) You train attention 2) You observe thoughts instead of reacting 3) Emotional patterns slowly get rewired 4) Stress response reduces while you are aware
So both are equally significant
Sleep = repair the system
Meditation= upgrade how the system works
Both can be considered as a separate in general to keep in it a simple way.
There are few topics like You Nidra where meditation is getting clubbed with Sleep but not sure about the practicality and complexity in doing so unless you are a spiritual practitioner for a very time.
