Have you seen some clerk in a bank looking from above his specs? The specs have slipped down on his nose, and he looks. Just look that way at me, towards me, as if you are looking from above your eyes, as if the eyes have slipped down a little on your nose and you are standing behind looking at me. Suddenly you will feel a change in the quality. Your focus changes; eyes become just doors. This becomes a meditation.
When hearing, just hear through the ears and remain aware of your inner center. When touching, just touch through the hand and remember the inner one who is hidden behind. From any sense you can have a feeling of the inner center, and every sense goes to the inner center.
