Honesty does not mean simply speaking your mind. Honesty means to be very clear about everything going on inside you. Where there is honesty, feelings become pure and clean. Honesty is where there are no other polluted thoughts or feelings inside.
Such clarity is reflected in your words; they will be filled with the power of truth, and spoken with ease and without hesitation. The genuine honesty cultivated within you is what will reach out and touch others.
