3.428

Attainment by non-attainment is precisely due to dark communion. The Way of dark communion is omnipresent in substance. Therefore the Laṅkāvatārasūtra says: "Because one knows that sentient beings are fundamentally entered into nirvāṇa, who alone does not attain it?" This then is fundamentally attained. Whereas earlier it spoke of shedding the aggregates or preserving the aggregates, calling it internal or external—such distinctions are not proper inquiries.
