Premanand Maharaj Ji
Why do I feel happy after getting something but never feel satisfied?
Contentment is not found in things
We are a part of Bhagwan and want imperishable happiness, so the perishable can never satisfy us, however much we enjoy, collect or obtain.
The imperishable can never find contentment in nature; it can never find contentment in the perishable, however much you enjoy, however much you gather, whatever you obtain.
