In summary, what the sutta description of the first jhāna is saying is the following: Become secluded from the hindrances. Don’t worry if there is still some background thinking. Pīti and sukha will be generated via the pāmojja (worldly joy) that arises from being secluded from the hindrances. Focus on the pīti and sukha; sustaining them enables you to remain in the first jhāna. Spread the pīti and sukha throughout your body.
