What is Vitakka, Avitakka and Savitakka according to Sutta?

What is Vitakka, Avitakka and Savitakka according to Sutta?
And what is their relation to Jhana?
I appreciate if you can explain this in both Sutta jhana (four fold) and Abhidhamm (five fold) formula.

AN 8.63 is the most clear of the EBT on this topic. (thereā€™s not much else, other than MN 128)
Here, the case for metta is given. The other 7 cases use the same formula (4bv brahmavihara, 4 sp (satipatthana)).

3 very interesting features to note:

  1. The 4sp and 4bv are all explicitly called ā€œsamadhiā€.
  2. sāta (satisfaction) is the equivalent of sukha in the 4j classification. Then you see how this 3 way samadhi maps into the 4 jhanas.
  3. later in the sutta, the Buddha says to do these 8 practices in all four postures for comfortable (phasu) abiding. This is a code phrase for saying, 4 jhanas can be done in all four postures, agreeing with AN 3.63, which coincidentally almost exactly the same number. The number three (3) is almost the same graphic image as the number (8) with a haircut.

(1. 4Bv #1: mettā me ceto-vimutti)

A very popular monk (Walasmulle Abhaya) in Sri Lanka teaches like this.
Is this incorrect?
It appears wrong. How do you rectify it?

=========

First Jhana = Savitakka (Vitakka), Savicara (vicara),Pithy,Sukaha,Ekagata
Second Jhana = Savitakka (avitakka), Savicara (avicara),Pithy,Sukaha,Ekagata
Third Jhana = Savitakka (avitakka), Savicara (avicara),Sukaha,Ekagata
Fourth Jhana = Savitakka (avitakka), Savicara (avicara),Ekagata

@frank
Can I say Savitakka and Vitakka are the same thing?
