When all mental ideation is thus little by little brought to an end; when all mental forms are gradually eradicated by the suppressive power of Yoga, the container of those forms--Space--being itself an idea, is then also suppressed along with the ideas of ego, time, and matter. In the apparent emptiness which results, the Real is experienced in all its mysterious fullness. Man comes as close to God as he may. But few mystics have the courage to take this final step. Most falter on its very edge, stricken by fear of the Unknown or by unfamiliarity with this mental territory. They stop and withdraw. The chance to venture beyond is lost and often does not recur for many years.
