Is attaining to Jhana possible for me?

Certain, good householder, would it be possible if leaving home and abound stinginess, since it's impossible for one still stingy and holding on things, a person who has no perfection in generosity, to gain Jhana.

Macchariya Suttas: Stinginess.

Now think about it, especially the matter gratitude.

Even such as access-concentration, the six Anussatis, would require certain deeds and behavior, conducts, to be able to clean ones mind.

What does one think of how many householders around here, seeking to avoid all basics, have even little chance to gain Jhana... No, no... not in this sphere around here. If some are good they can make use of meditation as a tool for compensation of daily wrong deeds and livelihood.

On the other hand there are many lay woman listed in Buddhas "who is who"-list for greatness in regard of Jhana, but those have been real Upasikas, Upasakas, not just "Buddhists"...

Gives surely much space for serious reflections or the more usual consumer protest - withdraw and rebellion. Ones choice, even caught inbetween.

The Buddha indeed recommended lay people to try to meditate, in the Piti Sutta:

Then Anathapindika the householder, surrounded by about 500 lay followers, went to the Blessed One and, on arrival, having bowed down to him, sat to one side. As he was sitting there the Blessed One said to him, "Householder, you have provided the community of monks with robes, alms food, lodgings, & medicinal requisites for the sick, but you shouldn't rest content with the thought, 'We have provided the community of monks with robes, alms food, lodgings, & medicinal requisites for the sick.' So you should train yourself, 'Let's periodically enter & remain in seclusion & rapture.' That's how you should train yourself."

But is it possible for lay people to successfully attain the state of jhana, at least the first jhana?

Ajaan Fuang addressed this very question in "Awareness Itself":

A student came to complain to Ajaan Fuang that she had been meditating for years, and still hadn't gotten anything out of it. His immediate response: "You don't meditate to 'get' anything. You meditate to let go."

What is the recommended daily duration? Please watch this YouTube video talk by Ven. Yuttadhammo entitled "Q&A: Short Meditation Sessions".

In SN 41.9, we find that the householder Citta, in his thirty years as a lay follower of Buddhism, was able to achieve and master the fourth jhana:

“But householder, how long have you been a lay follower?”

“It’s been thirty years, sir.”

“But householder, in these thirty years have you achieved any superhuman distinction in knowledge and vision worthy of the noble ones, a meditation at ease?”

“How, sir, could I not? For whenever I want, quite secluded from sensual pleasures, secluded from unskillful qualities, I enter and remain in the first absorption, which has the rapture and bliss born of seclusion, while placing the mind and keeping it connected. And whenever I want, as the placing of the mind and keeping it connected are stilled … I enter and remain in the second absorption. And whenever I want, with the fading away of rapture … I enter and remain in the third absorption. And whenever I want, giving up pleasure and pain … I enter and remain in the fourth absorption.

The best thing you can do is learning how to quickly overcome the hindrances as it will increase the actual time you spend effectively meditating beyond the treshold of jhana. Just sitting with hindrances is a waste of time.

I would advise to learn the development of various perceptions, the arousal of energy and to take note of the mind throughout the day in order to keep hindrances in check. Then when you see an opening to develop samadhi andor other factors you go for it.

At such times, monks, as the mind is sluggish, that is the wrong time to cultivate the enlightenment-factor[1] of tranquillity, the enlightenment-factor of concentration, the enlightenment-factor of equanimity. What is the reason? A sluggish mind is hard to arouse by these factors. [...] When the mind is agitated, that is the right time to cultivate the enlightenment-factors of tranquillity, concentration, equanimity. Why? Because an agitated mind is easy to calm[4] through these factors. https://www.accesstoinsight.org/tipitaka/sn/sn46/sn46.053.wlsh.html

It's definitely not necessary to sit 12 hours consequtively but if you do have days off you can try walking and sitting all day, switch between sitting & walking for as long as you are comfortable and delight in cleansing the mind by developing various perceptions, faculties and factors of enlightenment as you see fit.

I think if a person is fairly virtuous, has some less stressful work, few duties and is skilled in overcoming the hindrances then 90 minutes a day is plenty to get beyond the jhana treshold.

As to what their mind inclines to at that point, whether percepient of various pleasant feelings, lights & visions or is directed to the Deathless, that depends entirely on their faculties & prior development, either way it should absolutely be possible to occasionally get to a manyfold of profound jhana states for one like this.

Jhana means "to gaze, to focus" but the exact significance varies with the context. Here it signifies a high level of samadhi often translated "absorption."

I meditated in a theravada monastery in Thailand for ~ 3 months and experienced soft forms of Jhana (not those extreme ones you describe in your question). Many would say that that's not real Jhana, I just got a bit absorped by the meditation, saw a bright light although my eyes were closed or lost a bit the feeling on time. 90 min a day is more than enough to reach this absorption, too.

The founder of that monastery Ajan Buddhadasa Bikkhu had teached a lot about Jhana and his main point was that you don't need these extreme forms of Jhana. A bit of absorbtion is enough, just calm down your mind down to a point where it's still enough so that contentment (piti) and afterwards happiness (sukha) can arise. If you want to read more about this, this style of meditation, where you don't focus too much on Jhana is called Anapanasati.

I think for us who grew up with smartphones and constant entertainment, it's way more difficult to reach a very deep jhana. People 2000 y ago just didn't know that much other distractions.

In our practice of step four of Anapanasati, it is not necessary to try to enter jhana completely. In the practice of Anapanasati those very refined levels of concentration are not necessary. We only need to have a sufficient and appropriate level of concentration to continue with our practice, that is, enough samadhi that there are the feelings of piti and sukha (contentment and happiness). We need to use piti and sukha in the next steps of our study. If you can go on into jhana, into the material absorptions (rupa-jhana), that will be useful. It will make the next steps easier. Even if you do not reach jhana, as long as there is some piti and sukha you are doing fine. Now that will not be too difficult, will it?
