The fruit of prayer is faith. The fruit of faith is love. The fruit of love is service. The fruit of service is peace. Love cannot remain by itself - it has no meaning.
Love has to be put into action and that action is service.
For it is in giving that we receive, It is in pardoning, that we are pardoned, It is in dying that we are born to eternal life. And your gloom shall be like noonday. While thinking about the future, and about tomorrow's livelihood, if you don't let go of worldly affairs, if you don't practice the Way, and if you pass your days and nights in vain, you'll regret it. If thou art great after having been of little account, if thou art rich after having been poor, if thou art at the head of thy city, put on one side that thou hast reached the first rank. Harden not thy heart because of thy elevation, for thou hast become the steward of God's property.
