Keep your attention internal, not external, not worrying about what others see, but what the Self sees.
B.K.S. IyengarThat's the beauty of backbends. Emotionally we can never be disturbed, for the emotional centre becomes an extrovert. When you do Viparita Dandasana, your head looks backwards, but your conscious mind stretches everywhere. Study by observing how the mind gets regulated. You not only know the freedom in the spine, but also the freedom in the spirit.
B.K.S. IyengarAnything physical is always changing, therefore, its reality is not constant, not eternal.
