JOY, bliss, light and no thoughts.

After a certain period of time spent in the first Jhana, it could be a couple of years, the mind naturally steps back and observes it, having had its fill of this kind of happiness. The mind no longer wants to delve into the first Jhana because it has seen its impermanence and the disturbances it can create. Instead, the mind gravitates towards the second Jhana, seeking a calmer and finer form of happiness.

Second jhana 2 is joy, bliss, light and no thoughts.

The second Jhana provides a deeper dive into the feeling aspect, characterized by the feeling of joy, bliss, and light. It is a pleasurable and enjoyable state marked by the cessation of thought. The mind relinquished in being nourished by this happiness for a period of time.

Second jhana is like having many rivers and streams of water coursing through a dry land, from all directions, forming a lake. This innerspring keep filling until it overflows.

After the mind have had its fill, it becomes a watcher, observing the joy and happiness that arise naturally. The second Jhana is entered through memory, recalling the state of mind, feelings, and landscape of previous Jhana experiences.

The mind is progressively conditioned and reconditioned, shifting its perception and definition of happiness. Once the second Jhana is attained, the mind tends to gravitate towards it in subsequent meditation sessions, moving away from the disturbances of the first Jhana.
