The path of spiritual progress that the teachers of the Bengal school recommend is neither yoga nor jnana but bhakti. While the followers of the way of yoga emphasise the subjective aspect and those of the path of jnana both the subjective and objective aspect, the followers of the path of bhakti emphasize the objective aspect of consciousness .
Bhakti is the attitude of the mind , and jnana is the attitude of the intellect , both flow towards the Lord. In life to handle yourself, use your head , but to handle others, use your heart .
...there were three different ways of approaching God, viz., the ways of action ( karma ), knowledge ( jnana ), and devotion (bhakti). Of these, bhakti is the best among them, since it is the only means of salvation and the state of love (prema) and service (seva) which bhakti implies is better than even release.
...to attain liberation . There are three ways: The Karma Marga (the way of works or good deeds ), the jnana Marga (the way of wisdom or knowledge ), and the Bhakthi Marga (the way of devotion).
According to the Mahabharata also jnana seems to be the only way to attain emancipation (moksha); knowledge alone is capable of cleansing us of all our sins .
Jainism has a complex classification of jnana or knowledge, and the means of understanding reality.
