Most people can successfully practice aerobics or body building, for instance, without knowing human anatomy or without understanding at all what they are doing or why. Unfortunately (or, perhaps, fortunately), this is not so with yoga and meditation. Without knowing exactly the nature of this process it is impossible to correctly realize it and therefore there can be no true meditation.

Meditation is the highest yoga practice (this does not mean it is difficult!). In fact, very few people can really meditate, and this for two main reasons:
- very few know exactly what meditation is
- even fewer are willing to comply with it (lack of motivation).

Not everybody that stays motionless with the eyes closed is meditating. Meditation is an accurate science, therefore it cannot be practiced in total ignorance. Only those who study it with a serious inner motivation can successfully practice it.
