Quotes from the Lankavatara Sūtra
“By these four reasons, Mahamati, the waves of the evolving Vijnanas are stirred on the Alayavijnana which resembles the waters of a flood.” Vol.2
“Mahamati, this realm of the tathagatagarbha is primarily undefiled and is beyond all the speculative theories of the sravakas, pratyekabuddhas, and philosophers; but it appears to them devoid of purity, as it is soiled by these external defilements.” Vol. 7
Excerpts from An Exposition on the Lankavatara Sutra
