Jainism is no exception. Many of us go through rituals as a matter of tradition without questioning their usefulness. Jainism says that everything starts with how and what we think, day in and day out, and has given us ample means to generate right thoughts. First of all, we are all creatures of habit. Once we form a habit of doing anything, we tend to continue with it subconsciously.
Same thing happens with rituals.
For example, when we start doing a pooja or pratikraman, reciting Navkar Mantra, or doing any other kind of ritual every day, after a while we just go through it as matter of habit without any excuses. If we did not do this, most probably we would have spent the same time on non-spiritual worldly affairs. Secondly, many of our rituals require us to go to a temple or upashraya . This makes it easy for us to get away from a routine life and practice in a sacred environment full of positive vibrations. The chances of influencing our thought process in a holy place are much better than in our own homes.
