It gives you the joy of liberation and lasts throughout your future lives until you are
able to achieve enlightenment.
When we have developed loving kindness, we have achieved the priceless.
If you develop it in your mind-stream, you are the richest person.
Money and wealth are not reliable because it can collapse at any moment. If you have developed it in your heart,
it gives you a lot of happiness.
This is how I survived in prison Loving kindness is the most precious thing.
