In English
First, when you sit for meditation, recite a few verses on the glory of God, so that the thoughts that are scattered could be collected. Then gradually, while doing repetition of the name, draw before the mind’s eye the Form that that Name represents. When your mind wanders away from the recital of the Name, take it on to the picture of the Form. When it wanders away from the picture, lead it on to the Name. Let it dwell either on that sweetness or this. Treated thus, it can be easily tamed. The imaginary picture you have drawn will get transmuted into the emotional picture, dear to the heart and fixed in the memory; gradually will come the time when the Lord assumes that Form in order to fulfil your desire.
