Sometimes aloneness can be healing and therapeutic. It really depends on where you focus your intent. If while being alone you feel "lonely" you have allowed your ego to indulge in the feeling of being separated. However, if while being alone you can become meditative the influence of the ego will subside and the feeling of interconnectedness will arise. There really is no separation, that is merely the illusion of the ego. Don't allow your aloneness to become loneliness, otherwise you will miss something very subtle; use it as an opportunity to discover how vast your inner self is, and how it connects and merges with the infinite, divine consciousness. Within you is the entire universe, but only through awareness can it be perceived.
