My yoke is easy and my burden is light

  And in order not to be timid and low-spirited, always remember that where the sorrows of the world are, this is where there is the heavenly consolation of the Holy Spirit. The more our nature fights and opposes us, the more Grace helps us, which is stronger than nature. So, it is a yoke what we carry, but it is a sweet yoke, it is a load, but it is a light load. Because what nature makes heavy, Grace relaxes it in a miraculous way. It is sorrow and yoke, but the power of the mercy of the Divine Grace wears away the weight of the yoke and eliminates it. So, if with the thought of the yoke, you become timid and careless and lazy, let you become willing to fight with the thought of the mercy of the Divine Grace and even more with the expectations of the treasure of the eternal Happiness.
