[Footnote 2: The word Yâna is generally translated as vehicle, but a consideration of numerous contexts in which the word occurs seems to suggest that it means career or course or way, rather than vehicle (_Lalitavistara_, pp. 25, 38; _Prajñâpâramitâ_, pp. 24, 319; _Samâdhirâjasûtra_, p. 1; _Karu@nâpu@ndarîka_, p. 67; _La@nkâvatârasûtra_, pp. 68, 108, 132). The word Yâna is as old as the Upani@sads where we read of Devayâna and Pit@ryâna. There is no reason why this word should be taken in a different sense. We hear in _La@nkâvatâra_ of S'râvakayâna (career of the S'râvakas or the Theravâdin Buddhists), Pratyekabuddhayâna (the career of saints before the coming of the Buddha), Buddha yâna (career of the Buddhas), Ekayâna (one career), Devayâna (career of the gods), Brahmayâna (career of becoming a Brahmâ), Tathâgatayâna (career of a Tathâgata). In one place _Lankâvatâra_ says that ordinarily distinction is made between the three careers and one career and no career, but these distinctions are only for the ignorant (_Lankâvatâra_, p. 68).] 126 us the reason why one school was called Hînayâna whereas the other, which he professed, was called Mahâyâna. He says that, considered from the point of view of the ultimate goal of religion, the instructions, attempts, realization, and time, the Hînayâna occupies a lower and smaller place than the other called Mahâ (great) Yâna, and hence it is branded as Hîna (small, or low). This brings us to one of the fundamental points of distinction between Hînayâna and Mahâyâna. The ultimate good of an adherent of the Hînayâna is to attain his own nirvâ@na or salvation, whereas the ultimate goal of those who professed the Mahâyâna creed was not to seek their own salvation but to seek the salvation of all beings. So the Hînayâna goal was lower, and in consequence of that the instructions that its followers received, the attempts they undertook, and the results they achieved were narrower than that of the Mahâyâna adherents. A Hînayâna man had only a short business in attaining his own salvation, and this could be done in three lives, whereas a Mahâyâna adherent was prepared to work for infinite time in helping all beings to attain salvation. So the Hînayana adherents required only a short period of work and may from that point of view also be called _hîna,_ or lower. This point, though important from the point of view of the difference in the creed of the two schools, is not so from the point of view of philosophy. But there is another trait of the Mahâyânists which distinguishes them from the Hînayânists from the philosophical point of view. The Mahâyânists believed that all things were of a non-essential and indefinable character and void at bottom, whereas the Hînayânists only believed in the impermanence of all things, but did not proceed further than that.
