Deep inside the innermost recesses of the heart of every living being, there lies a conscious entity which is absolutely pure and Divine. This entity is indestructible, all-powerful and all-knowing. This entity is the true self of every living being. It transcends the body and the ever-changing nature of the individual mind. It is always one and the same and its nature is ever-new joy. This conscious entity is known as the individual soul. The experience of inner communion with the soul is realized through meditation on the inner light and sound. This science, the science of meditation, or the science of the soul, can be practiced by anyone irrespective of their religious and cultural background.
