A Cohen that has a Mum physical blemish is disqualified from doing Avoda in the Bais Hamikdash. The same Halacha applies to the animal brought for a Korban; it may not have a Mum. The Pesukim in this week’s Parsha enumerate a whole list of blemishes that are considered Mu’min. Notice how the first Mum of a Cohen אִ ישׁ ﬠִוֵּר :is כא יח blindness and the first Mum of the animals is: ֶרֶ תוַּﬠכב כב blindness. By the Cohen, four out of twelve Mu’min are in the eyes. We see the importance of sight. Besides the Inyan of Shmiras Einayim, we also need to have an Ayin Tova, and see only good in people.
This is why the Talmidim of Rabbi Akiva were Niftar, since there was Tzarus Ayin; no Fargining! No wonder Ahron became the Cohen Gadol because: his heart rejoiced יוחִ ת אָ לַ וּ דגְ ח בִּ מַ שָׂ ב שֶׁ לֵ with his brother’s greatness. He has a good eye! No Kin'ah! Being Dan L'kaf Zechus! R' Shlomo Wolbe Zatzal says in his Sefer on Chumash that those who see good in themselves, have an easier time seeing good in others.
If you are the critical type, at least don’t say your opinion. It proves your own Chisaron of not being an Ayin Tova. [Madregas HaAdam]. Insist on seeing only good and speaking only good, and you will be Zoche to greatness!
Ayin Tova needs to be a major issue in our lives; Please See [Only] Good In Me!
