Bhakti or devotion is ultimate focal point of all the Vedic scriptures. It is called par dharma, the supreme and final Divine dharma, because it joins a soul with God.
For example, in the Bhagavad Gita, the last instruction that Krishna gave to Arjuna was, "Sarva dharman parityayja." "Abandon all dharmas."
This might be a confusing statement, since Hinduism is the religion of dharma, and Krishn is supreme God. Isn't He working against Himself by saying this?
He adds right after this, "Mamekam sharanam vraj." "Surrender to Me alone."
In other words, do devotion or bhakti to God, but wholeheartedly. Don't mix it up with any other kind of aspiration that isn't related to finding perfect Divine happiness, even if it includes another teaching of dharma!
The ultimate Hindu dharma teaching is that all our actions, practices and knowledge culminate in bhakti for the attainment of supreme Divine Bliss. This is also our ultimate aim.
