Esoteric Teachings of the Tibetan Tantra
PART II: CHAPTER THREE

The [visual] form, sound, smell, taste, and [touch] stimuli are the five outer objects, from the seer to the feeler are the five senses, from the eye to the body are the five organs. In the terms of , they all belong to the Aggregation of Form. In the terms of Ayatana[r_nar:49] they belong to the ten Ayatanas of form; the Nonself-nature of them is thus pointed out by the stanza. The so-called mind (Sems) is the Aggregation of Consciousness, or the Ayatana of Consciousness. The so-called mind-function is the Aggregation of Feelings, Perceptions, and Emotions. The above stanza explains the Non-self-nature of sense-data or the Ayatana of Dharma. The form-seer and the sound-hearer mentioned in the stanza denote the egotistic conception of beings. In short, this stanza illustrates both the Clinging of Ego and the Clinging of Dharma.

The stanza says that the non-existence of essence means the absence or the non-existence of self-nature in all Dharmas and living beings. These sayings are the philosophy of the great master Mds'o-sg'yes as mentioned in his commentary. They imply the Voidness or non-existence of the self-nature or the non-existence of the definable nature of being--the self-being as expressed in many other sources.

This truth of the non-existence of self-nature, or the nonexistence of essence, or the never-come-into-being-self-nature, is by no means previously untrue but intentionally and subsequently verified through human reason and the holy edifications. This truth exists from the very beginning, as said in the stanza "to understand the truth as it is";

this clearly demonstrates the aspect of the "Originally true".

Guru Marpa said:

"On the bank of the Ganges river in the East,
Through the grace of the great Medrepa[r_nar:50],
I fully realized the original reality of the never-come-into-being.
This enlightenment kindles the void-nature of mind.
Clearly I beheld the original essence--the truth devoid of play-words,
And clearly saw the Three Bodies,
Whereby all the conceptualistic ideas in my mind were forever cleared up."

Thus Marpa's understanding of Mahamudra was procured mainly from the great master Medrepa, who, in this connection, particularly referred to the Thatness among the Ten Solenesses. As he said in a stanza: "It is neither with form nor without form." By this he meant the Soleness of the Originally True, not the Soleness With Form nor the Soleness Without Form. His disciple Lhan-j'ig-sg'yes-pai-rdor-rjes gave the exposition to this stanza in his commentary:
