The note associated with the quote indicates "The quotation given here does not occur in the extant Tibetan text of Bhavya's Madhyamakaratnapradipa, rather it paraphrases passages found on fols. 280-1 of the Derge canonical edn. of the text: dbu-ma, Vol. Tsha.". . . it is stated in the Jewel Lamp of the Madhyamaka by the master Bhavya (skal-Idan): "The Madhyamaka of the Prasangika and the Svatantrika is the coarse, Outer Madhyamaka. It should indeed be expressed by those who profess well-informed intelligence during debates with [extremist] Outsiders, during the composition of great treatises, and while establishing texts which concern supreme reasoning. However, when the subtle, inner Madhyamaka is experientially cultivated, one should meditate on the nature of Yogacara-Madhyamaka."
As far as I know the terms "Prasangika" and "Svatantrika" are Tibetan innovation when used to describe discrete approaches to Madhyamaka. So I'm guessing this "quote" is a rather loose "paraphrase" indeed. Can anyone shed some light on what it actually says in fols. 280-1 of the Derge canonical edn. of the Madhyamakaratnapradipa: dbu-ma, Vol. Tsha?
