Mind is seat of senses, to control mind is very important aspect. We need to understand our duty to train our mind. We need to discriminate and we need to chastise the mind sometimes, we need to distinguish what is bhakti and maya.
Complaining is the pastime of the mind engrossed in petty selfishness.
Whole things start with the mind. If mind is not purified then the words, through the words and through the body we will be committing sins and offences.
It is a natural tendency of mind to yield to maya. But it is our duty to take control of the mind and save it from succumbing to this illusive energy.
Mind always searches some reason to be dissatisfied.
Always go beyond the mind's limitations. If you do what your mind says you can, you will not end up doing anything.
