（1） To become one. As it is; just， exactly. Not two， not separate. Two things being different aspects of one thing， thus being inseparable. （2） Immediately， directly， now， then， accordingly. In terms of time shijianji 时间即 refers to a lack of any interval， while yishiji 异时即 refers to a lack of distinction between two things despite a time difference （anantaram）. （3） In Tiantai teaching there are three types of 即. The first is the non-separateness in the unity of two things; two things being a unity （erwuxianghe 二物相合）. The second is called beimianxiangfan 背面相翻 or the "relationship between front and back by turning over." This refers to something like a coin， which has the separate aspects of "heads" and "tails，" depending upon each perspective， but the coin is originally one thing. The third expression of singularity is called dangtiquanshi 当体全是， the "essence is identical，" which is exemplified by the fact that astringent persimmons and sweet persimmons are in essence， the same fruit; A， as it is， is B. This ideograph can also mean "absolutely the same，" a usage which originally began in Tiantai writings. （4） Supposing， even if.
