The only secret of attaining happiness is to learn how to appreciate our privileges in life. If we cultivate that sense of appreciation we shall be thankful, we shall be contented, and every moment we shall offer our thanks to God, for His gifts are many and enormous.
No meditation, no study, nothing can help in that direction, except one thing and that is to keep our eyes open to appreciate every little privilege in life, to admire every glimpse of beauty that comes before us, being thankful for every little love, kindness or affection shown to us by young or old, rich or poor, wise or foolish.
In this way, continually developing the faculty of appreciating life and devoting it to thanksgiving, we arrive at a bliss which no words can explain, a bliss which is beyond imagination: the bliss that we find ourselves having already entered the kingdom of God.
