I am also glad to learn that you are developing more and more a taste for thinking of Lord Krishna and His devotees. Such thinking is required, and you will see that as you think in this way, your taste for relishing the nectar of such meditation will increase more and more. This is called the limitless ocean of the nectar of devotion. This ocean is unending, and therefore the pleasure of relishing the nectar of this ocean is also increasing unendingly.
Letter to Krishna Devi, 2 November, 1969
