景師解云：尋思如實若就通說，地前上皆作此觀，地前可知，地上云何？前地已滿超入後地，如上文中，亦作此說。捨亂記中，有記加行道中，得作此觀，攝論文中，顯處說唯在十迴向四善根位修如此觀，尋思即在煖頂善根，四如實智在忍第一，尋思如實用智為體。尋者尋求，思者思量，尋求思量名義真妄未能決了名作尋思，若決定智名如實智，尋思如實皆是義名，四是數名，是即從數就義為名，名四尋思四如實。若別釋得名，名尋思者即是境，尋思即是推求之義，從境義為名；事尋思得名亦爾；自性是體，更互為客名為假立；假立尋思皆是義名，即從體義為名。

Master Jing explains: If investigation and accurate cognition are spoken of generally, this contemplation is practised both before and on the [bodhisattva] grounds. Before the grounds is understandable; what about on the grounds? When a preceding ground has been fulfilled, one transcends and enters a subsequent ground, as is also stated in the text above. In the notes on abandoning confusion, there is a note that during the path of preparation (prayogamārga), one can perform this contemplation. In the text of the Mahāyānasaṃgraha, it is explicitly said to be cultivated only at the stages of the ten dedications and the four roots of good: investigation is at the roots of good of heat and summit, while the four accurate cognitions are at forbearance and supreme dharma. Investigation and accurate cognition take wisdom (jñāna) as their essence. 'Vitarka' is seeking, and 'cetanā' is deliberating; when one seeks and deliberates on name, referent, reality, and falsity without yet reaching a determinate understanding, this is called performing investigation; if it is determinate cognition, it is called accurate cognition. 'Investigation' and 'accurate cognition' are both names based on meaning, while 'four' is a number name; thus they are named by joining the number to the meaning, called the four investigations and the four accurate cognitions. If their names are explained separately: 'investigation of names' means that name is the object, and investigation has the sense of searching out; it is named from the object and the meaning. The investigation of things is also named in this way. Intrinsic nature is the essence; their being mutually adventitious is called nominal designation. 'Nominal designation' and 'investigation' are both names based on meaning, named from essence and meaning.
