Q: My nerves are sensitive. Kindly tell me how to strengthen them, and also how to quieten my mind.
Solid nerves means patience, vigilance, endurance, capacity to break stones…. You must make your nerves strong by cultivating these qualities, and by bringing down quiet and peace. To get the stillness and peace you must first have silent aspiration in all the being for peace, then separate yourself from your mind, draw back and look at it from above. Actively watch the mind as it runs along. Don’t give sanction to the thoughts; if they are persistent reject them centrally, calmly, steadily, without struggle or effort or strain. Don’t involve yourself in the act of rejecting the thoughts. A vigilant will is essential lest you lose hold of self. You must be able to inwardly seize the mind and hold it… this is also necessary for active concentrated thinking. Both movements are mutually helpful…. With practice the mind comes under control, there will be quiet and stillness. After stillness is established, concentrate silently, consciously on the peace.
