A secret sympathy unites a great community. They recognize one another by a sign, by a look, by the magnetic atmosphere that each one emanates; by their silences more than by their words. Like the children of Light, they have the desire to know and to understand, to love and to believe. The countenances of the greatest among them are veiled by a strange melancholy; for the tragedy of the universe weighs heavily upon their hearts. They feel themselves responsible for it, as portions of the earthly providence that watches over human destiny. But through this veil there shines like an aureole of light the inward joy of those who behold Divinity. In the silence they are conscious of being united to all living creatures by an invisible thread.
In any activity that requires concentrated effort, the breath quite naturally plays a role. If you have ever tried to thread a needle or repair a watch, you might have observed that without even thinking about it the breath quiets and deepens. Singers, swimmers, people who struggle with panic attacks, and a host of others learn the importance of proper breathing in order to negotiate the respective tasks at hand. Thus, that the art of contemplative practice can be facilitated by the breath should come as no surprise.
