The $22 tier is the one that gives you access to this field, since you are not familiar with Patreon, let me explain something.
There are 3 tiers
$1 gratitude one, has a few fields and Mandalas, whatever in that tier you can download and keep, they will work even if you no longer pay.
$4.5 has the majority of the audios and includes whatever it is in the $1 tier. Same here, you can download and use even if you dont pay the monthly fee anymore and you can share with direct family, will work for them too.
$22 its the Premium one, it has a few extra special audios. Whatever is in this tier ONLY work as long as you are paying the monthly fee, and ONLY work for you the subscriber, not the parents or children or spouse. And this tier has all the audios and mandalas for the $1 and the $4.5 ones.
Here is the list of all of them per tier:
Enlightened States, Gumroad, Patreon, Sapien & Patreon Shop, & Spring Fields Database
