Be cautious

The Science of the Essence is not about buying the best or the most expensive.
Prestige, status and fashion do not enter into it.
Not every product by every manufacturer will have the essence.
Indeed most will be far off the mark.
Be discerning, be cautious, and do your research.

Sometimes, the original manufacturer is obscure and they focus on making only the one product.
The items may not be as expensive as lesser imitations.

The Science of the Essence need not be about consumer goods.
It can be applied to virtually everything.
