EPICTETUS. DISCOURSES. Book iii. §13. ¶1.AT what time soever thou wilt, it is in thy power, to retire into thyself, and to be at rest, and free from all businesses. A man cannot anywhither retire better, than to his own soul: he especially who is beforehand provided of such things within, which whensoever he doth withdraw himself to look in, may presently afford unto him perfect ease and tranquillity.
