Pīti is the word that Buddhists use for the dopaminergic tingles - the goosebumps and rush of electricity you feel through your body as you approach the finish line of a race or when a plan all comes together.
This is a propagation mechanism to ingraine insight into your neural network.
It also serves to stabilise and intensify focus during the deconditioning process, especially in sitting meditation. During sitting meditation it is the baseline state of your jhānas which are recommended to be cultivated for insight.
We shortcut around all this.
There are many ways to induce this dopaminergic surge and the neural settling of insight. Once you have taken your maladaptive thought-feeling loops to their conclusion during the process of equanimity encoding it's time to hit the install button and propagate the change.
You do this by getting a buzz on, through natural behavioural means.
My personal favourites are:
surging on the bike
blasting dance music and getting my rave on
the hot-bath/sauna cold-exposure combo
ice cream!
This is raising dopaminergic pressure and rewriting your synaptic potentiation. It will take whatever lessons you've been working on and lay the cables in your mind. If you are religious, you can have a particularly enjoyable and intense worship session instead.
This process happens naturally in your REM sleep phase, but you can hugely expedite the process through behavioural means during your waking hours.
Party your way to a better life!
