[Evdokia]

Krishnamurti was keen to describe "practice" as something one did without force and without a fixed point, something that I all to often see in reading Theravada works from various authors, not the Nikayas themselves.

This is because the simplicity of the Nikayas are difficult to comprehend where there is a lack of proper trust & discernment.

The Nikayas state about proper concentration:

And what is the faculty of concentration? There is the case where a monk, a disciple of the noble ones, making it his object to let go, attains concentration, attains singleness of mind.

SN 48.9 & 10 This was said by the Lord...Bhikkhus, a bhikkhu should so investigate that as he investigates, his consciousness is not distracted and diffused externally, and internally not fixed, and so that by not grasping anything he remains undisturbed. If his consciousness is not distracted and diffused externally, and internally not fixed, and if by not grasping anything he remains undisturbed, then there is no coming into existence of birth, ageing, death and suffering in the future. (John D. Ireland)

Iti 3.45 Now what, monks, is noble right concentration with its supports & requisite conditions? Any singleness of mind equipped with these seven factors — right view, right resolve, right speech, right action, right livelihood, right effort & right mindfulness — is called noble right concentration with its supports & requisite conditions.
