If that is so, how does samsara come about? In the beginning of Entering the Middle Way, Chandrakirti explains:
First you think “I” and cling to a self,
Then you think “mine” and cling to things.” (Ch. 1, v3ab)
Like a turning water wheel, you circle around in samsara due to clinging to an “I,” and once you have fixated on this self, there is “mine,” what belongs to you, and then comes the “other,” those seen as enemies, and so forth. This is the usual way that samsara appears—through clinging to “I” and “mine” and then “self” and “other.” This kind of grasping is the cause of all faults.
Nagarjuna writes, “Coming entirely from the cause of ignorance.” Due to ignorance, we take something to remain over time, which it cannot do; we grasp onto a referent where there is none; and we take something to have a root when it does not. Coarse clinging to things as real and the subtler clinging to characteristics as real are both caused by ignorance. Until you realize how ignorance is, you will continue to suffer. As much as you wish to be free of suffering that much effort should you make to be free of its cause, ignorance. If that is the case, what do you need to discard? Nagarjuna’s fourth line counsels:
Beginning, middle, and end are entirely left behind.
Grasping onto these three should be released back into their ground because these are all forms of clinging to permanence. And “permanence” is merely a concept imputed by your intellect; ultimately, it has no essence or core. As Nagarjuna states:
Without essence like a hollow plantain tree,
Like a city of gandharvas in the sky.
There are many examples for this absence of an essence, which is mistakenly taken to exist. Mind is caught in discursive thinking that projects a nonexistent reality. In the context of mahamudra, however, this process would be called the dynamism or the display of luminosity, clarity, or the cognizant quality (gsal ba) that is part of mind’s nature.
Not knowing this to be the case, you take these projections of your discursive mind to be real and wander, as Nagarjuna explains, in “a stupefying urban scene difficult to bear.” So benighted in taking phenomena to be real, you do not recognize that they are the dynamic energy and play of mind; you fixate on appearances and concretize them into self and other. Ultimately, however, the source of these appearances is primordial wisdom aware of its own nature. It is mere ignorance that creates the illusion of self and other, this projection of your afflictions, so you wander in a delusive world:
It’s a stupefying urban scene difficult to bear
Where beings appear as illusions.
