People change their opinions because their judgments are not correct. Sufferings in life are partly due to one s slavishness to moods and hasty judgments which one makes of persons and things. Spiritual practice is effort at fixity of consciousness. Ekatattva-Abhyasa, mentioned earlier, is such steadfastness in one reality, a concentration of oneself on a chosen ideal or a given mode of conduct. It is not easy either to cultivate Vairagya or be steady in Abhyasa.
Hard labour is necessary.
To keep oneself balanced in the midst of the tumult of the world is not a simple task. The process of Pratyahara will reveal that life is a battle, a struggle for existence. The mind becomes steady by conservation of energy through these efforts at self-control. When the powers of the senses get attuned to the mind, so that they have no existence of their own apart from the mind which is their source, there is Pratyahara. The prodigal sons now return home.
