Daf Yomi Nedarim 8
You’re sitting in Heaven about to board the rocket ship bound for planet Earth. As the world you know begins to disintegrate and disappear around you, your Father grabs you by the arm, looks into your eyes and says, ‘Promise Me, you will fulfill your mission on earth and accomplish great things!’ (Niddah 30b)
Rav Giddle quoted Rav: How do we know that one may promise to do a mitzvah? For King David declared, “I have sworn and maintained to keep the statutes of Your righteousness.”
Were we not already made to swear at Mt. Sinai to keep the mitzvos? The meaning of the Psalm is that a person may motivate himself to perform mitzvos by promising.
Unnecessarily taking an oath is generally frowned upon in Judaism. But sometimes you just have to. If promising to go to minyan every day will motivate you to get out of bed in the morning, then go for it, take the oath! If promising that you will not raise your voice around the house, then go ahead and swear to it. Anytime you believe that you can fortify your actions by swearing, it’s absolutely permissible and encouraged!
The truth is, like Rav says, we already all swore to do the right thing when we stood at Mt. Sinai. But even more than that, before you came into this world, you promised to achieve incredible things. It’s time to start reminding yourself of the promise you made to Father before you came down here into this world. And if that doesn’t do it for you, then make another promise to yourself that you will achieve greatness!
You were destined for awesomeness! The Almighty sent you here on a mission to be your very best. Keep reminding yourself that you have been chosen to accomplish amazing things. Keep promising to fulfill your destiny! You know what magnificent potential you have, it’s time to let the world know.
You made the promise up there. It’s time to promise once again in order to motivate yourself to accomplish your great destiny. May you merit reaching the level of the incredible individual you were sent here to become by constantly promising yourself that you will never quit until you become your very best!
