Mind
It is not too necessary to fix your mind on God, as it is to devote oneself to God. If one is well attracted to God, then the mind would by itself be fixed in Him.
As much concentration of mind is necessary in the path of Yoga, it is not so in the path of devotion. In devotion, there must be firmness of our relationship with God.
Peace comes from renunciation, not from concentration of mind.
Making the mind steady is not valuable, but the awareness of the independent and steady existence of the Self is valuable.
The need to remove the attraction of the world from the mind is greater, than wiping out the fickleness of mind.
So long as there is a tendency of removing the mind from the world and directing the same to God, till then there would be no controlling of mind. Mind could be controlled only when there is no acceptance of the existence of anything else, except God.
By unselfish feelings, the intellect becomes steady and by practice the mind. Liberation comes by the steadiness of intellect, but not from the steadiness of mind. The steadiness of mind endows one with occult powers.
The identity of mind is not with God but with nature. Therefore, mind can be merged in God, but cannot be fixed on Him.
