Let's take a mental worker who does something not so much physically as with his head. Usually there is an eight-hour workday.
At the same time, we have learned that the brain has a resource of about 4 hours for diligent activity.
It turns out that you either need to think less at work (but here there is a conflict with karma yoga and conscience before the employer) or switch to automatisms, delegate, etc. But you also don't need to leave work, as the yoga of training teaches.
There is time left after work, if the brain is still capable. At the same time, this time should not be at the expense of the family, again according to yoga training.
How to combine this?
