If you feel that you cannot read or you have no money to purchase book, never mind. Lord Caitanya has given you very simple path: chant Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare / Hare Rama, Hare Rama, Rama Rama, Hare Hare. If you chant this mantra with faith and devotion, without any offense, but simply by chanting you will realize yourself, you will realize God, Krsna, and your life will be successful.
