I understood the importance of thanking God for the things we receive. Gratitude is an eternal virtue. In humility we ask, and in gratitude we receive. The more we give thanks for the blessings we receive, the more open we become for further blessings. God's desire to bless is full to overflowing. If we will open our hearts and minds the receive blessings, we too will be filled to overflowing ... We may become like the angels themselves, helping others who are in need. In prayer and service our lights will always shine. Service is the oil to our lamps generated by compassion and love.
To listen to music or to sing a chant is to do something that has no practical purpose; it is just celebration and praise; it is just tasting the joy and beauty of life, the glory of God. Listening to it, even in the midst of a very purposeful day, reminds us to add the other dimension to our experience, the dimension of meaning, that makes it all worthwhile.
