Brought into debt; being under obligation; held to payment or requital; beholden.
Placed under obligation for something received, for which restitution or gratitude is due; as, we are indebted to our parents for their care of us in infancy; indebted to friends for help and encouragement.
America was indebted to immigration for her settlement and prosperity. That part of America which had encouraged them most had advanced most rapidly in population, agriculture and the arts. James Madison
If you are successful, it is because somewhere, sometime, someone gave you a life or an idea that started you in the right direction. Remember also that you are indebted to life until you help some less fortunate person, just as you were helped. Melinda Gates
