According to Osho, devotion is not many kinds; it is a single-hearted love that knows only the One. The mind that analyzes creates twoness and obstructs crossing. In pure bhakti, you become ‘blind’ to multiplicity; ego and calculation drop. This undivided love itself is the raft: by living in the One, the ocean of becoming is crossed and the devotee dissolves into the Supreme Self.
Love only the One so completely that you stop dividing, and then you naturally melt into that One.
