There are obvious tensions between attempts to do spiritual work and the needs and stresses of earning a living, caring for children and having a social life. Sadhana is best done in a setting where there are no disturbing sounds, and at periods when the practitioner expects no external demands on their attention.
No wonder many folk choose to go to a retreat centre to focus on their sadhana. In such an environment the work can get done in the company of like-minded people. Some retreats are conducted in almost total silence, while others request silence for limited periods within the schedule.
So what about people who cannot get away to a retreat centre? How easy is it to find half an hour or more in a busy day where you can sit without distractions, if there are other people in the house who may want your attention or may be making noise. And then when you actually have that time and space, how easy is it to switch into sadhana mode? That is before we get to the problem of a mantra practitioner making sounds which of course may not be appreciated by other household members.
I remember reading about when Swami Vivekananda was in Switzerland. A professor spoke to the swami while he was reading. Vivekananda made no reply. Later the professor asked his guest why he had ignored him. The swami replied that a yogi’s powers of concentration are such that they can shut out external stimuli. He added that one could put a lit match against a yogi’s skin and he would not feel it, if his mind was fully absorbed in a serious task. Most of us do not possess the gifts acquired by advanced yogis and yoginis. It is often hard to get the mind into a state where it is calm enough to embrace the opportunity to do sadhana. Sadhana should leave the practitioner feeling better. That is one motive for setting aside periods at home for spiritual practice. If you can find a place for meditation or mantra chanting in nature, even better.
