Conflicting desires arise in the mind. Because of these desires the mind is constantly lashed into waves. As long as these waves form, the mind is restless. In order to control these waves, which give rise to thoughts of a worldly and distracting nature, one must live a life of self-discipline.
The main thing is one-pointedness of mind. . . It is hard to control the mind, but it must be done. There is no other way. The more you think of the Lord, the more will other thoughts decrease. There must be a continuous flow of one thought—the thought of God— during the period of wakefulness. Then, at the time of meditation or in sleep, unbecoming thoughts will not find any loophole to enter.
We think we are loving without any selfish taint or hope of return, but deep within us there lurks the expectation that it should be returned and are quite at loss when we find the case to be not exactly up to our inmost wishes.
Remember always that children have brought their own karma with their birth and will develop accordingly in their own lines, and to hold before them the highest ideal by living the same is all that we can do to help them.
Swami Saradananda (a direct disciple of Sri Ramakrishna)
