It is good to be sensitive, but you must have choices; you must have selections. There are moments when you have to transcend the sensitivity, because in yoga we develop sensitivity, hypersensitivity. And those people who are sensitive make very good yogis. Do not try to suppress that. Do not have any negative opinion about your sensitive nature. Just practise yoga and you will find that your inherent quality of sensitivity will give you rich experience.
When sensitive people practise yoga, they take very little time to experience, but those who are blockheaded take a long time in yoga. So it is better to be sensitive than to be blunt.
