仁王經疏 3.239

3.239

Explanation: Fifth, the expedient means of the One Vehicle. Because the principle-essence is non-dual, it is called the One Vehicle. With regard to the phenomenon of the One Vehicle, skillfully knowing the distinct characteristics of sentient beings is called 'expedient means.' 'Non-dual characteristic' explains the One Vehicle above. Within it, 'penetrating all practice-characteristics' explains its expedient means. Furthermore, the *Suvarṇaprabhāsa-sūtra* says: 'The dharmadhātu is without differentiation; in order to cross over sentient beings, the three vehicles are explained with differentiation.' Also, the *Lotus Sūtra* says: 'All Buddhas, through the power of expedient means, within the One Buddha Vehicle explain three with differentiation.' The complete explanation of the One Vehicle is discussed as in a separate chapter.
