Mental purity will come through constant chanting of the divine name. This is the simplest way. You are trying to cross the ocean of transmigration, the cycle of birth and death. The mantra is the oar of the boat; it is the instrument you use to cross the samsara of your restless mind, with its unending thought waves. The mantra can also be compared to a ladder that you climb to reach the heights of God realization.
Mata AmritanandamayiChildren, in the present dark age of materialism, chanting the mantra is the easiest way for us to obtain inner purification and concentration. Japa can be done at any time, anywhere, without observing any rule regarding the purity of mind and body. Japa can be done while engaged in any task.
Mata AmritanandamayiThe person who constantly studies without doing spiritual practice is like the fool who attempts to live in the blueprint of a house.
