 In 1402, Tsongkhapa, with his teacher Rendawa (Red mda' ba gzhon nu blo gros), (1349–1412) (Roloff 2009) and others, at the temple of Namstedeng (rNam rtsed ldeng/lding) convened a gathering of monks with the intention of reinvigorating the Buddhist order. From this came Tsongkhapa's short, but influential works on basic Buddhist morality (Sk. prātimokṣa) that in turn laid the foundation for the importance some Gelukpa monasteries would place on a stricter adherence to the monastic code. In 1403 his influential works on ethical codes for bodhisattvas (Byang chub gzhung lam) (Tatz 1987) and for tantric practitioners (rTsa ltung rnam bshad) (Sparham 2005) appeared. His separate explanations of the three ethical codes (Tib. sdom gsum) are distinguished by the centrality they give to basic morality, the importance the bodhisattva's code retains in tantra, and in the antinomian tantras the presence of a separate prātimokṣa-like ordination ritual built around a codification of of ethical conduct specific to tantric practitioners.
