The best and the easiest method to attain that glorious goal of establishment in the Truth is to listen to the Guru over and over again.
But if such frequent personal contact with the Guru is not possible, the next best alternative is to take, as often as possible, a deep thought of the Truth as first visualized in the presence of the Guru. This brings you into the climate of the Truth everytime, and you experience it afresh.
-- Sri Atmananda
