True Chashivus and Greatness Is Reached Through Simcha And Gratitude

Only empty people get sad and disturbed. Ahron was married to Elisheva, the sister of Nachshon, whose family were the Shoroshim of Dovid HaMelech who said: ּכוֹסִּי ְרָויָה — my life is overflowing with Simcha. Perhaps this is also the significance of the eight Begadim of the Cohen Gadol. A person who appreciates the phenomenal body that Hashem gave him, and is constantly overjoyed about his healthy heart, lungs, liver, kidneys; his abilities [e.g. to walk, talk, eat, breathe, smell, see, hear, think, etc. etc.] deserves eight Bigdei Kehuna L'chavod u’Le’Sifares.
