Unfortunately, I'll have to decline this one.... it's a Triratna/FWBO site. Nothing against them, but the search engine is specific to Theravada.
Alas this means that even excellent sites like Buddhanet with a lot of Theravada content cannot be included in whole, because including them in whole would also automatically include their Mahayana content.
What is the final conviction that comes when radical attention is razor-edge sharp? That the object of the mind is mind-made (manomaya). (Ven. Ñāṇananda)
Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'. (Snp 3.6)
