Spiritual journey is about knowing who you are. Helping social causes expands consciousness to an extent. Dont get obsessed about them. Enlightenment is the real goal.
Many organizations get over obsessed about solving social issues because that becomes main stream but keep in mind the world (mind is a dream). Your goal is to awaken from the dream.
While your involved in these causes do your service not from charity perspective but use it to feel one with people you serve. As the feeling of oneness grows into One the illusion begins to melt and you will find mediation and life has a better meaning and focussed drive.
