Mindfulness is for developing stable attention that brings a calm inner peace.
The capacity for a stable attention increases awareness, intelligence and harmony.

The mental peace brought about by mindfulness has deeply therapeutic healing properties. Mindfulness Therapy is known as the ‘third wave’ in psychotherapy, following psychoanalysis and cognitive behavioral therapy, and is having remarkable success. Through rigorous studies, mindfulness training has been proven effective in the treatment of a wide variety of mental and emotional disturbances such as anxiety, stress, depression and addiction, as well as boosting the body’s immune system, neurological functioning, and self-healing capacities.

Mindfulness allows detachment from the thinking mind which is judgmental by nature. Once detached from the restlessness of the thinking mind, mindfulness allows our awareness to settle down to a naturally calm state of stillness and clarity.

While mindfulness training undoubtedly brings inner peace and has enormous therapeutic and healing capacities, it also is a sensitive tool to explore and contemplate our spiritual essence and the fundamental nature of our own mind. 

Mindfulness is a precise tool to penetrate deep into our own awareness, facilitating an in-depth understanding of its nature and qualities.
