"When a large crowd gathered, with people from one town after another journeying to Jesus, he spoke in a parable. "A sower went out to sow his seed. And as he sowed, some seed fell on the path and was trampled, and the birds of the sky ate it up. Some seed fell on rocky ground, and when it grew , it withered for lack of moisture. Some seed fell among thorns, and the thorns grew with it and choked it. And some seed fell on good soil, and when it grew, it produced fruit a hundredfold." After saying this, he called out, "Whoever has ears to hear ought to hear."
-Luke 8: 4-8
"Return every day to the garden of your soul to root out any brambles that might choke the seed, the teaching you were given, and to till the soil. I mean, every day strip your heart clean."
- St Catherine of Siena
