How about you just follow the steps of anapanasati and see what happens? Watch the breath until piti arises and go from there.
You seem to be caught in the thicket of views. In reality, Jhana is readily accessible to those who spend more time just watching the breath and less time wondering where it will take them
Gain and loss, status and disgrace,
censure and praise, pleasure and pain:
these conditions among human beings are inconstant,
impermanent, subject to change.
Knowing this, the wise person, mindful,
ponders these changing conditions.
Desirable things don’t charm the mind,
undesirable ones bring no resistance.
His welcoming and rebelling are scattered,
gone to their end,
do not exist.
- Lokavipatti Sutta
