Water or fire as such cannot move a train; they must both co-operate to produce a third thing, steam. Similarly, Bhakthi, jnaana, or karma must all lead to the achievement of equanimity; otherwise, they are simply pseudo.
Clouds that flit across the sky cannot induce the blue depths of space. Similarly, Sorrows and disasters cannot injure one who has determination and faith.
