Knowledge that is paid for will be longer remembered.
A mitzvah that costs money is worth more than one that costs nothing.
Feel no sadness because of evil thoughts: it only strengthens them.
Prayers truly from the heart open all doors in Heaven.
Just as your hand, held before the eye, can hide the tallest mountain, so this small earthly life keeps us from seeing the vast radiance that fills the core of the universe.
All new beginnings require that you unlock a new door.
