Thank you for your great question and your kind words!
As BapDada mentioned today (3-31-13) in the avyakt Murli, it is about “balance.” Enjoy life as a whole, with everything that it brings. Solitude by being “by yourself” is a first and perhaps necessary step for many in the spiritual path. That will change. You will learn to be by “yourself” while with others. When there is that inner power and “will” for self transformation, you will find opportunities, rather than challenges to “test” your stage.
You may express your need to be alone in some occasions. Perhaps “being alone” is not something that some people will understand. They will think that you are depressed and that they need to “cheer you up.” Express your need to “re-charge” yourself to be with them afterwards, with greater energy and enthusiasm.
Spirituality is the expression of love and power. When there is that “power” you will not need to “choose your company.” Spirituality has many stages, and certainly we should be able to recognize, first grade from high school. That is, spirituality is honesty with the self, and because of that; with others.
“Solitude” is important because it allows you to be with everyone being “you.” Otherwise, you will not be YOU but learn to be “them.”
This is not meant as separation but as a reminder than being aware and conscious is not what everyone is interested in.
