Adam ki yakriv meekem korban Lashem min habehemah
Adam ki yakriv, a person who wishes to come close to the RBSO, should look at a korban and learn about his own ability.
Any person who declares an animal he owns to be a korban, instantly transforms that animal into kodesh or kodshei kodoshim. Merely by saying the words, even without doing anything to the animal.
All the more so when a person speaks words of Torah and Tefila before HKBH, how powerful those words are.
