As Kabbalah says – there are three main driving forces in us – for the ego which is all about “whatever I want, I should get…” – the emotions which are Tendencies – basically divides into love which is a desire for something or someone, that I feel is pleasurable to me, or that is like me… or will be a benefit to me – Fear which is the desire to not encounter a stimuli that I believe will be painful or shameful – and finally the mind – which is an objective Observer of reality and eventually can bring us to the recognition – that just living a life of Desire – is meaningless
