We may experience weariness, physical pain, sloth or torpor during our meditation periods.
We should not abandon our practice because of sloth or torpor. It does not matter how sleepy we become, we keep sitting until it disappears. As soon as this happens, concentration will arise.
Although laziness may make us want to give up, we must put up with it. We will overcome the hindrance right there.
Restlessness and wandering thoughts can put an end to meditation practice if we do not have enough wisdom. When this happens, just observe it and continue to do so until the restless stops. The mind will then be free and Samadhi will occur.
Hindrances are only walls. If we can get through the door, we will be face to face with wisdom.
