In ‘Day by Day with Bhagavan’ (10.5.46) Sri Devaraja Mudaliar writes about an incident that happened in Bhagavan’s hall :
One afternoon Krishna Jivrajani asked Bhagavan, “Suppose there is some disturbance during meditation like mosquito bites, should one persist in meditation and try to bear the bites and ignore the interruption or drive the mosquitoes away and continue meditation?”
Bhagavan answered, “You must do as you find most convenient. You will not attain mukti simply because you refrain from driving the mosquitoes away. The thing is to attain one pointedness and then to attain Manonasa. Whether you do this by putting up with the mosquito bites or driving the mosquitoes away is left to you. If you are completely absorbed in your meditation you will not know that the mosquitoes are biting you. Till you attain the stage why should you not drive mosquitoes away?”
