In actuality, the seven paramāṇus each individually form gross matter; they do not speak of mutual assistance. According to the teachers of the New Sarvāstivāda, their seven paramāṇus gather in the same aggregation and are close to one another, mutually assisting and imparting power, each forming its large appearance; it is not by combining into an appearance through resemblance that it first becomes gross. Furthermore, as with forms such as long and short, there is an appearance of a long paramāṇu and an appearance of a short paramāṇu.
