Life has two aspects, of which one is known and the other unknown except to a few. This unknown aspect of life may be called the immortal life, the eternal life; and the known aspect may be called mortal life, as it is the experience we have through our physical being which gives us the evidence of life. The immortal life exists but most of us do not know it. This is because of our lack of knowledge, and not because the immortal does not exist. Everything we have in this life, whether an object, a living being, a thought, a condition, a deed, or an experience, breaks up and dies away. Every one of these things has its birth and death; sooner or later what is composed must be decomposed, what is made must break, what is built must be destroyed, and what is visible must disappear.
