Nothing is easier than to fool oneself.
Purity of heart and intensity of devotion and aspiration are that which draw one nearer to God.
One cannot indulge in one’s lower appetites and yet remain spiritually pure.
Perfect self-restraint and purification of mind and heart are the price that the aspirant has to pay for spiritual enlightenment.
As long as the body is there, as long as the mind is there, there will be their drawbacks, in weaker or stronger shades. Constant vigilance is the price that the aspirant must pay.
