Jewel of the Essence of Good Explanation

It is correct for us to say that the way of the perfections is the way which is
"shared," and that the way of the secret word is the way which is "not
shared." This is because such a description is found in a great number of
authoritative works. The Steps of the Path to Buddhahood, for example, speaks
about "how to train oneself in the way which is shared—the way of the
perfections, and how to train oneself in the way which is not shared—the way
of the secret word." The Concise Steps as well includes the lines:
Thus is the path which is shared,
The one which is required
At both the stage of the cause
As well as the stage of result
In the higher way,
The path which is supreme.
There is another description that mentions the "way for common disciples"
and the "way for unique disciples." It is apparent that these expressions,
[which use the same Tibetan term,] have the same connotation as "shared"
and "not shared" above.

Someone might assert that "In the context of the way of the perfections, the
way of the secret word is not accepted." This though is incorrect, for the Brief
Commentary includes a section where it states that presenting the bodies of a
Buddha as being exactly four is moreover not inconsistent with the way of the
secret word. This section reads: "Nor moreover is this inconsistent with the
other division of the teachings."
