For those seeking to enhance their practice of the meditation technology, the cultivation of mindfulness and clear comprehension (sati-sampajañña) are two indispensable tools leading to the improvement of one's ability to establish mindfulness.
The reference to meditation technology in this quotation is in reference to the technology that is taught by Gotama in suttas that discuss meditation in general and in particular. There are many, although two such examples are the Anapanasati Sutta and the Kayagatasati Sutta in the Majjhima Nikaya. But the one sutta that I had in mind and which is already referenced in the post that this quote is found in is the Mahasatipatthana Sutta (DN 22) and the four establishments of mindfulness. Please note that each of these suttas is referencing the establishment of mindfulness of specific objects. I would have thought that was fairly obvious to the attentive reader.
While some may choose not to characterize these sutta instructions as a "technology," I do because it is, by all the evidence we have available to us today, what Gotama taught.
