SN 22.8 three akusala thoughts and animitta samadhi

SN 22.8

three akusala thoughts cease in "well established" 4sp, which in comparison to MN 78, would refer to a samadhi of quality less than first jhana.

Tayome, bhikkhave, akusalavitakkā—	There are these three unskillful thoughts.
kāmavitakko, byāpādavitakko, vihiṃsāvitakko.	Sensual, malicious, and cruel thoughts.
Ime ca bhikkhave, tayo akusalavitakkā kva aparisesā nirujjhanti?	And where do these three unskillful thoughts cease without anything left over?
Catūsu vā satipaṭṭhānesu suppatiṭṭhitacittassa viharato animittaṃ vā samādhiṃ bhāvayato.	In those who meditate with their mind firmly established in the four kinds of rememberfulness meditation; or who develop signless undistractible-lucidity.
Yāvañcidaṃ, bhikkhave, alameva animitto samādhi bhāvetuṃ.	Just this much is quite enough motivation to develop signless undistractible-lucidity.
Animitto, bhikkhave, samādhi bhāvito bahulīkato mahapphalo hoti mahānisaṃso.	When signless undistractible-lucidity is developed and cultivated it is very fruitful and beneficial.
