What does it mean to be sensitive? 

To be cognizant of colour and form, of what people say and of your response to it; to be considerate, to have good taste, good manners; not to be rough, not to hurt people either physically or inwardly and be unaware of it; to see a beautiful thing and linger with it; to listen tentatively without being bored to everything that is said, so that the mind becomes acute, sharp,

All this is sensitivity, is it not? So is there much difference between sensitivity and awareness? 

I don't think so.⁠

You see, as long as your mind is condemning, judging, forming opinions, concluding, it is neither aware nor sensitive. 

When you are rude to people, when you pick flowers and throw them away, when you ill-treat animals, when you scratch your name on the furniture or break the leg of a chair, when you are unpunctual to meals and have bad manners in general, it all indicates insensitivity, does it not? It indicates a mind that is not capable of alert adjustment. And surely it is part of education to help the student to be sensitive, so that he will not merely conform or resist, but will be awake to the whole movement of life. 

The people who are sensitive in life may suffer much more than those who are insensitive; but if they understand and go beyond their suffering they will discover extraordinary things.⁠
