Note that the texts here appear to be arranged according to the “three trainings” (བསླབ་པ་གསུམ་, bslab ba gsum) of discipline (ཚུལ་འཁྲིམས་, tshul 'khrims), concentration (ཏིང་ངེ་འཛིན་, ting nge 'dzin), and insight (ཤེས་རབ་, shes rab). Zhuchen’s catalog renders the second of these as “the supreme mind” (ལྷག་པའི་སེམས་, lhag pa’i sems).
