俱舍論記 2.174

2.174

「然大德說至假立觸名」者，此即第四解。四大論師中法救，敬其德不多序其名，故稱大德。以實而言微不相觸，但由無間極隣近，假立觸名。

"However, the Bhadanta says ... touch is established only metaphorically": this is the fourth explanation. Dharmatrāta among the four great masters: out of respect for his virtue his name is rarely set forth, so he is called the Bhadanta. In reality, paramāṇus do not touch one another; merely because of their being without interval and in extreme proximity, the name 'touch' is established metaphorically.
