Pranayama helps to develop intensity of concentration, clarity of thought, and a dynamic personality. It brings out the most constructive power latent in a person. In Patanjali's words " Tatah ksheeyate Prakashavarnam" which means it removes restrictions to illuminated consciousness. A great Acharya Mahapragya says " it is not only an exercise of respiration but it is a significant technique of dissociating karma. So as to burn impure particles, fire is needed; similarly, for burning impurity of the sense-organs, it is very essential to practice Pranayama".
