Solitude does not necessarily mean living apart from others; rather, it means never living apart from one's self. It is not about the absence of other people, it is about being fully present to ourselves, whether or not we are with others.
Silence, waiting, empty stillness: these are not achievements we accomplish but living forces beyond ourselves which we learn to flow with, surrender to. There is a River of Stillness, or Musical Silence, or Beautiful Darkness flowing through the heart of al beings which we enter into when we allow ourselves to rest in quiet, in silence, waiting. The contemplative way is to begin listening to this dancing stillness.
