The body needs an optimum and defined stream of food to maintain its basics to carry on with limbs to perform the activities of life.
The heart and mind need a moral diet to make life carry on with the optimum pace of the soul.
That could only be derived from the blessings of saints on the subject of life.
Once body mind and heart pick the true pace then it is like tracking the truth of true success they are in but through the blessings of saints.
With love and affection, one serves the lotus feet of saints and attains the impossible with all ease.
