until an expert answer arrives, I thought I will try this..freeing the mind I will breathe in, vimocayaṁ cittaṁ
It is one way of freeing the mind, this word "vimocayam" is used when the teaching uses breath as a vehicle that leads to the freedom of mind such as in MN 118.
When successful it leads to the same goal. Whether you use breath, or 4 brahma viharas, or Satipatthana as in SN 47.42, or the Similes of the 4 jhanas like the soap powder, lake on the mountain peak, water lilies in a pond, a figure encased in pure white, they all do the
same job.
The freed mind is listed as a wishless mind, signless mind or empty mind, or freed by wisdom, Panna-vimutti. Doctrinal wise, it is the same thing. Mind has shed the samsaric aspect, or samsaric consciounesss that gives birth to love, hatred and confusion.
One is home free. I hope this helps, until we have the Pali analysed
Best
PS I also read vimōcana (विमोचन).—n S vimōkṣaṇa n S Liberating...
not sure whether it is the same in Pali, anyways it is something to do with release or liberation,
released by breath??
