The Nature of Now
Without a calm mind, one cannot experience the ultimate reality, the underlying oneness, as one’s own Self.
Spiritual practices (prayer, meditation, deep breathing, yoga) have value because they remove the agitation of the mind.
A peaceful mind, steady in awareness, can understand the purest teaching at the most subtle level.
Therefore the practical advice of the sages is to not bother anyone and not be bothered by others.
To reach the highest state and to know one’s own Heart as the Self, one has to become absolutely indifferent to both external and internal perceptions.
