Positive Mitzvah 246: Laws of Claims
Exodus 22:8 "In every case of trespass...in which one can say: This is it"'

Ari and Izzy were playing ball on the lawn.

Suddenly, Ari felt his glove beginning to slip of his hand.

He shouted to Izzy to wait a second, but Izzy threw the ball anyway. It landed in the street sewer because Ari wasn't ready to catch it.

"Hey! I asked you to wait!" Ari yelled.

"I'm sorry, I didn't hear you," Izzy answered.

"Yes you did. I could tell! Now you've got to buy me a new ball!" Ari demanded.

"No I don't" Izzy protested.

In cases like these, where an argument arises and people disagree about who bears responsibility for a loss or damage, the Torah teaches us how to come to a fair decision.

If you're serious about something, it has a fixed time. If you're earnest about getting something done and the phone rings, you ignore it. The spiritual side of your life is not a hobby nor a luxury -- it is your purpose of existence. When you are learning Torah, or meditating or in prayer, nothing else exists.
Your spiritual career should have at least equal priority to your worldly career.
