We are a composition of the external and internal energies of god. The gross external energy is the gross material body and the subtle external energy – is the mind, ego and intelligence. Behind both energies is the soul, the internal energy. Siddha Yoga is a system to control the mind by using our material body. It is like controlling the infuriate horses of a carrot. When one become deeper in sensual, they loses their identity and forget self.
One of the most beneficial aspect of yogic meditation is it reduces stress and improve emotional well being. It helps us to manage and diminish stress. It dilute unhealthy and aggressive actions by increasing self-awareness and balanced thought process.
