Look carefully at the 2 plates in this drawing. The inner circle in both the drawings are of the same diameter. Plate 1 has the ability to carry more than the Plate 2. Now take off Plate 1 for many days , put is aside and start using only plate 2. Now our mind is conditioned to take on less.
Geometry does work in unimaginable ways. So does illusion.
In life the same applies. We are conditioned in purchasing big or lured into buying bigger properties, bigger cars, bigger diamonds etc. But what we need at heart is determined by what we really need and not by our wants. You be the judge on your REAL need and wants.
