We can say that there are three types of hearts. The first one is the physical, which causes problems of diseases that are mainly due to overeating and sedentary habits. By regulating the diet and by proper exercises, the heart disease can be prevented. It is necessary to keep the body in a fit condition to do service. In China, people follow certain type of yoga called "Taichi". They get up early in the morning and do this exercise. India has a rich tradition of yoga which relates to breathing, sitting and walking. A massive educative campaign is needed, especially in the rural areas, to prevent heart diseases, by propagating such Yogic exercises.
The second heart is that of the Chakra, which is the seat of emotions, radiating love, compassion and hatred too. This accounts for the psychological aspect of disease of the heart patient. That is why they administer holistic medicine nowadays.
The third one is the spiritual heart. The "Purusha" or Supreme Power resides in the inner most recess of this spiritual heart. This is referred to as the many-splendoured effulgent Jyothi. The three-dimensioned (Physical, Emotional and Spiritual) heart is the secret of human consciousness, which is the direct like with the Divine. This is what the great sages of the Upanishads proclaimed when they had a vision of the Divine. They experienced the Supreme Purusha as the effulgent one shining with the brilliance of a thousand suns.
