St. Thérèse of Lisieux lived a life full of God's love, and she called her pathway to God the "little way." It was a simple spirituality of following God like a little child, letting him guide her in every way possible.
While the "little way" may be simple, it is not always easy to follow and requires a great deal amount of trust in God's providence.
Here is the collect prayer for her feast day, asking God for the grace to walk in her "little way."
