had neither beauty nor purpose, but only heat and motion.
Gradually, when her vapours were condensed into a unified rounded

a necklace of diamonds. So with our soul. When the heat and
motion of blind impulses and passions distract it on all sides,
we can neither give nor receive anything truly. But when we find
our centre in our soul by the power of self-restraint, by the

are apart, then all our isolated impressions reduce themselves to
wisdom, and all our momentary impulses of heart find their
completion in love; then all the petty details of our life reveal
an infinite purpose, and all our thoughts and deeds unite
themselves inseparably in an internal harmony.

joy is when it reaches the infinite one within its eternal unity.
Hence the saying of the Upanishad, _Only those of tranquil minds,
