The greatest obstacle on the path of surrender is ahamkaara (egoism) and mamakaara (mineness or possessiveness). It is
something that has been inhering to your personality since ages,
sending its tentacles deeper and deeper with the experience of
every succeeding life. It can be removed only by the twin
detergents of discrimination and renunciation. Bhakthi is the water
to wash away this dirt of ages and the soap of Japam, Dhyaanam and Yoga (repetition of God's name, meditation and communion)
will help to remove it quicker and more effectively.
