What is Mastery of reflectionJhana mastery They say to master jhana you must master five factors. I understand the first four but mastery of reflection is kind of leaving me unsure. I think i get it. Once you come out of the jhana state, you refect on the absorption factors like you do the jhana factors you focus on each until the hindrances is gone. But what are these absotbtion factors. Do i just think about it or stsrt a second meditations on each factor and be aware of them? How do i know what these factors are and distinguish them? They also say there different absorption factor to reflect on. Can you help me understand
These five powers have to be mastered, DeusIIXII, for the purpose to develop right view, for the purpose to gain proper concentraion, for the purpose of release:

(the) first

❋ Namo tassa bhagavato arahato sammā-sambuddhassa ❋


  There are these five strengths for one in training. Which five? Strength of conviction, strength of conscience, strength of concern, strength of persistence, &amp; strength of discernment.
  
  And what is strength of conviction? ...Vitthara Sutta: (Strengths) in Detail


Since certain prerequisites are possible missing, for one living at home: Development of the first six recollections/reflections can be done "no" matter how busy you are, if the busy is according to the Dhamma: AN 11.13

Since lack of stinginess is prerequisiten


  "Without abandoning these five qualities, one is incapable of entering &amp; remaining in the second jhana... the third jhana... the fourth jhana; incapable of realizing the fruit of stream-entry... the fruit of once-returning... the fruit of non-returning... arahantship. Which five? Stinginess as to one's monastery [lodgings], stinginess as to one's family [of supporters], stinginess as to one's gains, stinginess as to one's status, and ingratitude. Without abandoning these five qualities, one is incapable of entering &amp; remaining in the second jhana... the third jhana... the fourth jhana; one is incapable realizing the fruit of stream-entry... the fruit of once-returning... the fruit of non-returning... arahantship.
  
  Macchariya Suttas: Stinginess


Lack of Macchariya is reached by entering the stream. So as long difficulty in devotion, gratitude, precepts, e.g. having not really get known the Dhamma by proper attention, no right view yet, it's good to focus on the base. Then it might be possible, like for this generous and devoted man, to take on: fear &amp; animosity are stilled

Much joyful effort is wished!

Addition, since just coming aware again: There is a "new" book, a gift of Dhamma to give, surely very usefullin this regard:


   The Five Faculties : Putting Wisdom in Charge of the Mind, by Ṭhānissaro Bhikkhu. (revised October 22, 2017) In May of 2017, members of Le Refuge, a Buddhist group located near Marseilles, invited me to lead an nine-day retreat on the topic of the five faculties (indrīya): conviction, persistence, mindfulness, concentration, and discernment. These are a set of qualities that the Buddha numbered among his most important teachings. When put in charge of the mind, they lead all the way to awakening. Taken together, they deal primarily with the practice of meditation, which makes them a good framework for a meditation retreat. However, the first faculty—conviction—focuses on questions of self and world: what kinds of happiness you believe you are capable of attaining, along with what kind of happiness you believe can be found in the world. This means that the five faculties also provide an excellent framework for covering the entire practice of the Buddha’s teachings, both on retreat and in the world at large. (Source)


Note that "reflection", which you used in the question, is actually wisdom/"knowing" (paññā), or discrimination, such as reflection requires sati (mindfullness) and paññā.

Since knowledge at first place, having hear/read the good Dhamma, this might be most usefull to fullfil the answers demand on it's root.
