For Bhartṛhari, a fifth-century Indian grammarian-philosopher, all conscious beings are capable of what he called pratibhā, a flash of indescribable intuitive understanding such that one knows what the present object means and what to do with it. Such an understanding, if correct, amounts to a mode of knowing that may best be termed knowing-what. This essay attempts to expound Bhartr. hari’s conception of pratibhā in relation to the notions of meaning, understanding, and knowing, with a view to suggesting its relevance for contemporary studies of related topics.
