BEIS Torah Ohr continues: This is the mistake that working people make because in their view they think that they cannot Daven as much as those who sit and study Torah all day but the opposite is true, they can Daven even better. Because, of the superiority of light that comes from the darkness.
This relates to what the Alter Rebbe writes in Iggeres Hakodesh of the book of Tanya: “On Shabbos and on Yom Tov working people also have time and therefore also have the obligation of the Avodah of prayer with greater enthusiasm.
It is understood that in order to have the possibility of the Avodah of prayer on Shabbos and on Yom Tov one must also have this Avodah of prayer on the week day as well. Because as our sages say “Someone who has exerted effort before the eve of Shabbos can eat on Shabbos”. Just as it is with regards to eating on Shabbos so too is it regarding prayer on Shabbos because there is already a relationship between the Shabbos Davening and the Shabbos meals as it is explained in Chassidus that the Shabbos prayers are like the blessings on the meals.
So, from here it is understood that there needs to be an Avodah of prayer even in the days of the week (even working people).
But in the days of the week since there is no time the Avodah is not so much in time but the main thing is in the intention ‘Better a little but with intention... [It can be said that a little bit of stretching it out (Even in time) shall also be done in the week, but they shall not lead the services since they cannot extend their prayers long enough to discharge someone else’s obligation, because since there are those that do have time to lengthen their prayers like teachers or those that are supported by parents or in-laws it would be better that they lead the services.
There is added lesson which is understood from this that those who are engaged in Torah study have no scope for this mistake which means that only those who are engaged in work can make such a mistake that they cannot Daven for so long as those who sit and study Torah. But those who sit and study Torah, even though a person may forgive himself he cannot make this same
