Flint Sparks wrote this about Nothing Missing:

We tend to think we are a problem to be solved. Consciously or unconsciously, we have this uneasy feeling that something is missing. Something is not quite right. We habitually defend against this sense of lack, we organise experience to deal with our vulnerability and construct and cling to the idea of self as a defence against the fear of groundlessness. From a psychological point of view, we think the problem is our conditioning. If we could only identify and then work with our conditioning, then we might find relief from our shaky identity and establish a strong sense of self that is robust and healthy. From a spiritual point of view, we hope to either affirm a belief system we can rely on forever or dedicate ourselves to a set of practices that will eventually end our suffering and assuage the existential sense of lack. The result is that we either work endlessly towards psychological self-improvement or become a perpetual spiritual ‘seeker’ looking for nirvana.

Both paths to salvation are flawed because they both miss the shadow aspect of this pervasive ‘sense of lack’. Our deepest fears are not that we will never be good enough or that we will eventually die. The shadow fear, the one that we least want to face, is that the sense of self we rely on for our identity is, in truth, groundless and without substance.

Nothing is missing. We are always perfectly ourselves. The thing we cling to the most – our sense of self – is not worthy of our faith and trust. We cling to our conditioning and forsake our True Nature. Drawing on the teachings of the Buddha, contemporary psychotherapy, and mindfulness practices, we work together to soften our seeming requirement for self-improvement and open to the possibility of profound self-acceptance.
