There is a practice which can bring the concentration into heart-consciousness. Cultivate a feeling of warm, devoted love for the Overself, along with an indrawing into the heart. Concentrate the attention there physically. Also, the breath should be held with an air of expectancy in the same way that you hold your breath during the moment before a famous lecturer, say, starts an important public speech, or, like a hen when she's trying to hatch an egg, giving it warmth and expectancy and concentration.
As attentiveness deepens, you will feel a drawing-in from all directions. When you get a feeling (which may come during meditation or at any time) that you are at the centre of a circle, this will indicate that you have touched the heart-consciousness. The exercise requires you to think less and feel more.
It helps markedly if you think of the heart as a cave. You as a conscious being have to enter this cave, pass through its entire length, until you gradually see a tiny gleam of light at its other end. This light grows stronger and stronger as you approach it. (But this can be actually done only after the mind and emotions have been sufficiently quieted, so the preliminary phase of concentrating must first be gone through.) Fasten all your attention unwaveringly upon this gleam until it expands and envelopes you in a great light. Think of it as the Overself seen and felt. A later exercise and stage is to feel it only, to banish seeing it altogether.
