~ Sri Ramana Maharshi
Really there are only two methods, Enquiry and devotion. One leads to the other. A devotee concentrates on God.
A seeker, follower of the Jnana-marga seeks the Self. The practice is equally difficult for both.
Since God is verily the Self, love of the Self is love of the God and that is bhakti. Jnana and Bhakti are thus one and the same.
Service, like prayers, japa and even businesss done in God’s name, lead to the highest Goal; Self-realization.
Complete effacement of the ego is necessary to conquer destiny, whether you achieve this effacement through Self enquiry or through bhakti-marga.
Self-enquiry is possible for mature minds, not for immature ones.
For the immature ones, japa nama, worship of images, pranayama, visualizing a pillar of light and similar yogic and spiritual and religious practices have been prescribed.
