Why am I feeling like not doing anything? Is it okay to not want to meditate or do seva?
It indicates that you’re very tired, mentally and physically. So rest well, but eat less. If you eat a lot and rest then restlessness increases. Eat little less so that the food gets digested well and then rest. That will take out all the tiredness.
You may feel lazy exercising all alone, but if you exercise in a group it will help you get over lethargy in the body and sluggishness in the mind.
