Swami has said that every individual will receive their own calling from the Lord that resides in their heart. Have the Form of the Lord before you when you sit quietly in a place for meditation, and have His Name. Do not change these two, but stick to the ones that please you most. When you meditate, the mind often runs after something else, it takes another road. You have then to plug that outlet by means of the Name and the Form and see that the even flow of your thoughts toward the Lord is not interrupted; if it happens again, use the Name and the Form again, quickly.
For beginners in meditation, it is advised to recite a few verses on the glory of God, so that the thoughts that are scattered could be collected. Then gradually, while doing a repetition of the name, draw before the mind’s eye the Form that that Name represents.
