A Sattwic man will do virtuous actions. A Rajasic and Tamasic man will perform non-virtuous actions. It is the guna that goads a man to do actions. The Self or Brahman is actionless. He is the silent witness.
Fear is an effect of ignorance.
Identification with the body causes fear. Blind attachment to the body, wife, children, house, property etc. is the cause of fear. The sage who has realised the Self is absolutely fearless. If you lead a life of honesty and truthfulness, if you devoutly observe the precepts of the scriptures without doubting, if you lead a life of right conduct, and if you remember God always, you will become fearless. Purity of understanding, cleanliness of life or purity of heart.
