Mind is Atma Sakti. It is an illusory power of God or Brahman. The seat of the mind is heart. It is formed out of the subtlest essence of food. A Vritti is a wave that arises in the mind-lake. There are three Gunas in the mind, viz., Sattva (purity), Rajas (passion) and Tamas (inertia, darkness). Control the Vrittis. Increase your Sattva. If you entertain thoughts of hatred you are really a murderer of that man against whom you foster such thoughts. You are committing suicide, because those thoughts rebound upon only you. Hatred ceases only by love and not by hatred. Your thoughts, sentiments, moods and emotions produce their strong impressions on the face. The face is like an advertisement board wherein is what is going in the mind is specified. As the first thought is the thought “I” and as this thought “I” is at the base of all other thoughts. Ahamkara is the seed for the mind. Buddhi (Bheda Buddhi) is the cause for this differentiation (this little “I”, the self-arrogating false personality), and is again the cause of Ahamkara. Destroy this false egoism and the Bheda Buddhi by Brahma Bhava, Vichara and rest in your own natural Satchidananda Svarupa.
