Aloneness is a noun that describes the physical state of having no one else (or no friends) present. Loneliness is a noun that describes the aching sadness one can suffer from feeling alone. The two are often conflated in modern society -- but they don't have to be.
Could it be that it is in your greatest moments of loneliness, you are most called to be by yourself because there is something stirring within that seeks your undivided attention and perhaps has a message for you?
Whether grieving the loss of our own life, or another's, we each have the capacity to see past the veils of separation. If our hearts are willing, grieving becomes the gateway to loving awareness, the entry into our own awakened nature.
What if you knew that you were never alone -- that you were always being guided by a personal source of spiritual guidance? If you knew and experienced this, you would undoubtedly feel much safer and more peaceful.
