Progress in devotion or meditation means the attainment of concentration. Never lose the sight of the Divine Form which you have pictured for yourself. Don't allow the mind to wander on distractions. Be convinced that the distractions of sight and sound are designed to scatter your attention away from the Divine Form. Be on your guard, do not be deluded  and never forget the auspicious form. Picture in yourself the Divine Lord, in whom is immersed all creation. What you will experience and when depends upon His Grace. Your mission is to practice one-pointed concentration on Him. It does not depend upon the length of time, or the number of births you have taken. Some may realize the goal even in a few days. It completely depends upon your dedication, devotion and relentless practice. The time cannot be calculated or reasoned out.  It is all His Grace.

- Sandeha Nivarini.

For the deeds done in ignorance, repentance is the way to make amends and to earn pardon. 
Not to repeat the same deed is the sign of the morally strong. - Baba
