The path of the spiritual traveler is therefore one of waking (awareness of self as soul) and sleeping (under the illusion that we are our body), waking and sleeping. We tend to fluctuate between the two (like dawn and dusk) until we find stability in soul-consciousness. This is why it is important to awaken and stay awake, and why it's important to give our mind and intellect good spiritual food (knowledge) and exercise (meditation) every day to keep them fresh and alert. Being conscious of the soul, acting from that consciousness, the scars (habits and tendencies) left by past actions based on illusions of bodily awareness are healed. Discipline is necessary for growth and personal transformation if you want to obtain satisfying and permanent results. If not, the old habits continue to rule in your life. The evidence that our discipline in the practice of meditation is working is mental lightness and an increasing easiness in our interactions with others.
