“To be satisfied is the highest and best of all blessings.  There is in the whole of existence no one who is truly satisfied  with worldly achievements.  One who pursues the pleasures of this world never attains them to the extent that he would like.  The fulfillment never equals the expectation.  He remains eternally hungry.

Only the one who sets spiritual happiness as his goal who sees in all worldly matters only means to that end, who in truth and sincerity desires nothing but the service of Hashem – he is the one who is satisfied with G-d’s bounty.  He is perpetually filled with happiness – in this world too. ~ Strive For Truth
