Aim for Love
In Krishna-bhakti (devotion), sadhana or practice is quiet simply understood as the various means toward love. The methods by which one may fall in love, in particular to be always conscious of the object of love, is sadhana-bhakti-- devotion in practice. If love (bhava) is not the consciously desired outcome then proportionately a person's sadhana will be ineffective. That is the conclusion of Sri Rupa (1489-1564).
