Let the mind run wherever it likes; just be careful not to follow it, seeking to discover where it is going! It will then wander about for some time as the fancy takes it. Soon, getting tired and exhausted, it will come back to you! It is like a little child that knows nothing. Since the mother is following it and calling it back, it gets courage and confidence to run forward in any direction. But if the mother does not run behind the child and instead quietly retraces her steps, the child too, of its own accord, will run back to the mother! Carry on with the remembrance and meditation of the Divine Name and Form you like best and in the manner you are accustomed to. In this way, you will acquire one-pointedness (ekagratha) and realise your heart’s desire.

- Dhyana Vahini, Chap 8: 'Onepointedness is Essential for Meditation'.
