Swami Vishwananda tells you today:

All that we do in our daily life, what we work, our spiritual path is only to attain one thing – to attain the purity of Love, to become self-realised. But to attain this purity, to attain and to realise the Self, one can’t without devotion. Only through Bhakti. Without Bhakti it’s difficult. Like Shree Krishna said in the Gita; “Cast away all dogma. Cast away all from the mind, and surrender to me.” Then only true love can be realised. Otherwise, if you see, with Jnani, it's only in the mind. I don’t say it’s not good, its good. But it will lead you only to a certain level. Karma Yoga is very good to help. But if you’re not helping with the right attitude, it still brings you only to one level. Whereas Bhakti; devotion, what Shree Krishna said to Uddhava; “ Above all the Yoga, I prefer Bhakti Yoga. I prefer the Yoga of devotion. Where the devotees and the Lord become one, when there is no difference that stays.
