(LTC, pp.
Tsongkhapa-s-Qualms-About-Early-Tibetan-Interpretations-of-Madhyamaka-Philosophy
Underlying the above issues is the crucial question of the exact nature of the relationship between the Madhyamaka philosophy of emptiness (sunyatti) and the ultimate standpoint of Vajrayana Buddhism. Like many of his Tibetan predecessors Tsongkhapa shared the view that Tantra represents the pinnacle of spiritual awakening in Mahayana Buddhism. This is true also of great Tibetan masters like Marpa Lotsawa, Sakya Paw;iita, Buton, and of course many of the Kadam teachers including the Indian master Atisa himself. However, what seriously concerned Tsong- khapa was the widespread misconceptions associated with Tantra which he believed to be pervasive at his time in Tibet. Among these was the widespread relegation-in some cases leading to eventual negation-of ethics on the grounds that the Tantra proposes a standpoint which is non- jUdgmental, and beyond all forms of dichotomy and polarities. Ethics was perceived to be relevant only to those of weak mind, whereas a true spiritual aspirant whose mind was receptive to the mysteries of Tantra could and should transcend the strictures of conventional morality. Such attitudes, according to Tsongkhapa, led to a climate of moral decline in ancient Tibet. From the above, we can surmise that Tsongkhapa saw an

intimate link between epistemological scepticism, philosophical nihilism
and moral relativism. Not only does one naturally lead to the other, one could almost say that they are all different aspects of the same coin.
CONCLUSION
In this paper, I have attempted to "reconstruct" what I see as Tsongkha_ pa's key concerns about certain Tibetan interpretations of Madhyamaka philosophy. I have suggested that these qualms can be grouped under three main categories: i) Tsongkhapa's objections against what he sees as nihilistic interpretations of the Prasangika-Madhyamaka thought; ii) Tsongkhapa's objections against Shentong absolutism, and finally iii) Tsongkhapa's fears about residual influences of Hva-shang's quietist anti- rationalism in certain elements of Tibetan thought. Methodologically, I have argued that "listening" to the author's own voice is critical if we are to appreciate the dynamics behind the philosophical works of a historical thinker like Tsongkhapa. One very important consequence of identifying
an author's central concerns underlying his writings is that it gives a greater coherence and cogency to the author's overall project (if there is one). Certainly, in the case of Tsongkhapa, we know that one of the principal objectives underlying his Madhyamaka writings is to demon- strate that the Madhyamaka dialectics do not negate the reality of every- day world, especially ethics and religious activity. Related to this is also the aim of developing a reading of Madhyamaka philosophy in such a way that it can be consistently situated within an integrated system where the Madhyamaka philosophy of emptiness stands alongside Dharmakirti's epistemology and Asanga and Vasubandhu's ablzidharma psychology and
Vajrayana's meditative praxis. Throughout, I have endeavoured to engage "philosophically" with the issues which were of concern to Tsongkhapa so that they could be not only made comprehensible to us, but can also resonate with phiiosophical and soteriological questions which occupy people's mind to this day.

Buddhist scholarship. . See Tucci (1958), Demieville (1967), Stein (1987), Houston (1980). Y. lmaeda (1975) Uournal asiatique, 1975, p . 140) has raised doubts about the factuality of the debate. However, I think that the weight of the historical evidence is too great to deny that this event took place. Earliest Tibetan sources which deal extensively with the debate are: sBa bzhed, and its revised version Zhabs btags 1M, Ne'u PaD<;lita's Chos 'byung, Sakya PaQ. <;lita's sDom gsum rab dbye, and ButOn Rinchen Drup's Chos 'byung, and Pawo Tsuglak Trengwa's (1504-1566) Chos 'byung mkhas pa'i dga' stan. For a contemporary discussion of the wider philosophical and religious implications of the debate, see Ruegg (1989), especially parts II, III, and IV.
9. Tibetan sources characterise the dispute as centred on the question of whether or not "enlightenment" is attained through a gradual and prolonged process of reflection and praxis or in the form of an instantaneous experience. A central point at issue here is the role of discursive analysis in one's path to enlightenment. "Simultaneists" reject this, while the "gradualists" insist on its indispensability. Hence, my choice of the terms here.

It is difiicult to discern whether this date is accurate. Even if we were to accept this, it is far from clear whether Tsongkhapa really meant this ode to signal his departure from the main- stream of Tibetan Madhyamaka thought. On the surface, the text appears to be nothing more than a passionate expressIon of admiration of the Buddha for having taught the prinCIples of dependent originatlon

Thurman takes this to be referring to Tsongkh"pa's rebuttal of four types of objections against the Madhyamaka philosophy of emptiness (LTC, pp. 50-89). Sec Thurman (1984), pp. 326-28, footnotes 1 12, 113 & 1 14. Although related, these are two quill. ' distinct issues. One relates specifically with the refutation of w hat Tsongkhapa sees as four main r;lisreadings of Prasangika-Madhyamaka's ontological nominalism. In contrast, the rebuttal of the four objections in LTC is part of Tsongkhapa's overall argument against those who, when identifying the objection of negation, go beyond the scope of reason's capacity to negate (dgag bya ngos 'dzin khyab che bal. This is dearly an error which must be corrected in future reprints of Thurman's book.

Tsongkhapa's reading of these passages can be found in LTC, pp. 136-144. 40. In LTC, Tsongkhapa identifies four main premises of the "no-thesis" view. that (i) critical reasoning that enquires into the question of whether or no? things exist in terms of their intrinsic being, negates all phenomena; (ii) phenomena such as production, cessation, etc. cannot be objects of valid cognitions for it has been stated in the Madhyamaka scriptures that percept_ ions like visual, auditory, olfactory and so on cannot be accepted as valid; (iii) phenomena such as production, cessation, etc. cannot be accepted as existent even on the conventional level for the reason that negates production on the ultimate level also negates it on the conventional level as well; and (iv) there is nothing that does not fall into the categories of existence, nonexistence, both, and neither, and all these four possibilities have been revealed to be untenable. Tsongkhapa subjects these four premises to detailed criticism in LTC, pp. 23-89. For Khedrup-Je's critique of the "no-thesis" view, see Cabez6n
(1992), pp. 102-112.
41. Interestingly, a number of writers on Madhyamaka in modern scholarship
appear to share the view that the Madhyamika literally has no views of his own. For example, B. K. Matilal characterises the Prasangika-Madhyamaka's standpoint as "non-committal. " See Matilal (1971), p. 164.

RongtOn identifies three types of thesis: 1) thesis that is accepted for the sake of others under special circumstances, 2) thesis accepted both by oneself and others, and 3) thesis accepted only by oneself.

Future studies may reveal the identity of the proponents of these views. But even at this early stage it can be surmised that Tsongkhapa's primary concern in this letter appears to be that there still remains a strong legacy of Hva- shang's views in Tibet.
