Three debts

Three debts are akin to the three mortgages on one’s life. The first debt is to God and the repayment requires regular prayers and worship, and selfless service to all of God’s creatures. The second debt is to the sages and saints, who have revealed truths in scriptures. The repayment of this debt arises from service to the needy, handicapped, sick and poor, and less fortunate. The third debt is to one’s ancestors, parents and teachers. The repayment of this debt means raising one’s family in accordance with the moral and ethical principles of dharma.
