Depends on the level of one's devotion

I'm having ascetics in mind

Many philosophers, who were equally devoted to thought, complained about the same difficulties

okay

But we are to consider thought way more easier than life of an ascetic

so by "ascetic" do you mean something along the lines of "lives alone, owns minimal things, minimal distractions" etc?

*fixed*

yes

okay

and this is for what purpose?

Meditation comes to mind

Impossible to pursue inside any household with other people

why?

In fact, the existence of monkish institutions, serves so monks could encourage each other as well

why can you not meditate in a household exactly?

Get some guidance in meditative techniques, try it and you will see

no, be specific. is it noise? being too close to your worldly cares?

the latter is a good point, among others

presence of other beings in one way or another makes optimal conditions more difficult to achieve

in terms of space

silence

schedules

preparation of meals

okay, then a few items for your consideration

so it's basically noise + proximity + chores so far

the very organization of daily life in accordance with certain standards

noise: you are the man of the house, make people behave. If they do not behave, hit them.

that is why God gave you great physical power

that very act of hitting somebody would be exactly the type of distraction you want to avoid

proximity: you could leave your household and go somewhere else to meditate, even set aside an entire unscheduled day for it

chores: see above

now this last part is important for you to consider

it perfecty fits the description of "sub-optimal"

you don't want to do that, or have to do that

it's the introduction of passions and emotions where you least want them

well obviously, but you do what you need to in order to get results, that is how life works

an old brahmin is supposed to deed his possessions over to his oldest son, then become a wandering holy hermit and go live in the woods

the fact that family and max ascetic spiritual life are not compatible is worked into the system

once the man's grandchildren are born, he alone or he and his wife if he wants can go be wandering monk hermits in the woods until they drop dead mid prayer or meditation or whatever

there are strict guidelines on how much they may own, what they may do, how much food they can eat and from where they can procure it

so basically they did your thing already
