Does emptiness & no-self work together? Emptiness seems to be very prevalent in Dhamma after Theravada.
But I have seen that it still exists in Theravada, it has just been ignored compared to other teachings.

Why is emptiness ignored so much in Theravada &amp; can emptiness be harmonious alongside the teaching of no-self?

If my question is not clear, please inform me. :)

Metta to all!
Yes the buddha says that conditioned things are empty, which means they are empty of self like he says so in https://suttacentral.net/sn35.85/en/bodhi or even https://suttacentral.net/sa273/en/choong

In fact he even says that knowing that things are empty, not self, dukkha and all that is the trigger for liberation


  ‘The first absorption is a basis for ending the defilements.’ That’s
  what I said, but why did I say it? Take a mendicant who, quite
  secluded from sensual pleasures, secluded from unskillful qualities,
  enters and remains in the first absorption. They contemplate the
  phenomena there—included in form, feeling, perception, choices, and
  consciousness—as impermanent, as suffering, as diseased, as an
  abscess, as a dart, as misery, as an affliction, as alien, as falling
  apart, as empty, as not-self. They turn their mind away from those
  things, and apply it to the deathless: ‘This is peaceful; this is
  sublime—that is, the stilling of all activities, the letting go of all
  attachments, the ending of craving, fading away, cessation,
  extinguishment.’
