Why variations in Yoga practice?

Some teachers would tell you that variation is not good and it’s enough to perform 12 (14, 20, …) basic asanas every session. (There are large well known chains of Yoga centers applying this approach.)

In my opinion this may be well true – especially if one is an advanced Yogi, well motivated and seeking meditative state in few asanas he/she performs. (It may also be useful if teachers in above-mentioned Yoga centers are in general poor teachers – it’s easier to learn how to teach 12 poses and then force that approach on everybody…)

For most of the practitioners variations in practice are important. Here is why:

There are many possible variations: different asanas, different pace, order of asanas, time for practice, place, in a group or not, etc.
They important – because they challenge mind and body – and that is keeping your practice alive.
If there are no variations – beginner in Yoga risks to become dull and bored with practice, will start to miss sessions and then stop practicing altogether.
Actively engaged mind – is more likely to be awake, aware and mindful of practice – and these qualities take time to develop to become a second nature. – And later, if we choose in the future to have more meditative practices – developed mindfulness and concentration skills would help us.
Actively engaged body and “confused” every time muscles – tend to develop much more actively. Muscles that repeat same routine – tend to stagnate.
If variation is in trying different practices/”styles”, different centers in different cities, countries, etc. – this helps to develop understanding and patience toward other human beings and ultimately – compassion.
Variations keep beginners (and advanced practitioners too!) interested! – This for many is a huge component of motivation…
