“The simplest and, I am not afraid to say, sufficient prayer rule for a good, pious life is attentively and humbly reading the morning and evening prayers. If it’s possible, read a chapter from the Gospels and the Epistles daily. Again, if you have the possibility and strength, read a kathisma or more from the Psalter. We will definitely add here the prayers before and after meals, before wor…after completing the workday. Anything else can be added with the advice of your spiritual father…”
(Priest Dimitry Shishkin on building a prayer rule in pravoslavie)
