You can’t get a taste of something you don’t come into contact with. So first you have to find someone with some significant quantity of divine love. Then you have to try to see things the way that person does, feel things, understand things the way that person does – even if its only for a few moments, like in a kīrtan while that person is singing and you can feel at one with their expression. If you do this you will get an initial taste for Krishna’s bhakti, and that will enable you to “practice” (cultivate) that taste in your own self by doing similarly as that person does (i.e. kīrtan, for example), especially if you can have that person’s guidance somehow.
