Our emotions and feelings provoke us to think in a certain way. Our thoughts will become pure if our intentions are pure. Pure thoughts inspire us to perform pure tasks. Consequently, pure actions, pure thoughts and pure intentions provoke us to behave well. This is why purity is of utmost importance for the intellect.
For this reason, it is necessary to perform satsang by meeting saints, study our scriptures, contemplate and reflect on them. Whatever we see, hear and read leaves a deep image on our feelings, thoughts and behaviour.
