What happens when your tank is empty, and you’ve got nothing left to give?
It's not really about what you give, it 's about what you give up. What you let go. 

We can always give love. We can always send lovingkindness and compassion.

We can give to ourselves if it is from the heart. Love yourself by loving all beings. Free yourself by loving all beings. When you love yourself in a virtuous way, you see yourself as you humbly see everyone. 

Anyway, If your tank is empty for giving then remember there are 7 other parts of the eightfold path other than giving that can be practiced by monastics    and    laypeople.  -m e t t a
