Frontal Lobe February 21, 2014:  is the seat for our discrete ability, planning ability, emotions, self-motivation. During Dhyana frontal lobe will be serene and stable.

Parietal Lobe: is the centre which will help about our consciousness of the surroundings, time sense. While doing Dhyana its activation is slowed down.

Thalamus: Consciousness, sensory organs control, communication responsibility, concentration are major jobs of thalamus. While in Dhyana the flow of communications are reduced.

Reticular Formation: Alertness, fighting spirit, running away from danger making us ready to face eventualities through electrical impulses as Alfa Waves are responses of Reticular Formation

Alfa Waves are responsible for Reticular Formation. During Dhyana and Yoga the responses of Alfa Waves are reduced, slowly Theta Waves will increase creating calm and serene atmosphere to brain and in turn to whole human body. This rejenuvates both Mind and Body resulting in immuno-modulation and better quality life.

In Charaka Samhitha & Susruta Samhitha herbs are mentioned which will help in improving the calmness of body and mind like Aswagandha (recommended for insomnia, as a rejenuvator and aphrodisiac)Brahmi, Shankapushpi etc. Hence the combination of Dhyana, Ayurveda and proper eating habits go a long way in proving 100 years healthy, happy life.
