Spirituality is an important tool for healing. I have just read a book I found very helpful: Jack Kornfield, A Path With A Heart, Bantam Books, 1993.
Some quotes:
"The greatest lesson I have learneed is that the universal must be wedded to the personal to be fulfilled in spiritual life."
"The body is present, the heart is soft and open, the mind is attentive."
"The seeds of wisdom, peace and wholeness are within each of our difficulties."
"This freedom and awakening, and this alone, is the purpose of any genuine spiritual path."
" Expanding our spirtitual practice is actually a process of expanding our heart, of widening our circle of insight and compassion to gradually include the whole of our life."
