Premanand Maharaj Ji

Is there a practice to build concentration for meditation?

Gaze at a point while chanting

Fix your gaze on one point and chant Radha inwardly. Hold the gaze as long as you can, and concentration becomes very strong.

Fix a point, and just chant Radha Radha inwardly while you keep looking at that point. When the eyes blink, close them, then open them again.
