VIJNAN
From the above proclamation it is very clear that the human body is not merely a mass of 70 constituents (e.g. blood, flesh etc.) or biochemical (e.g. fat, carbohydrates etc.). It is made up of not only 1) juices 2) blood 3) flesh 4) muscle 5) bones 6) fat 7) sperm but that deep within lies a divine principle. All the above 7 constituents are influenced by the 7 Chakras and our body unknowingly remains healthy or unhealthy due to this influence. If the state of the secret inner recesses of the soul related to the 7 Chakras, remain balanced it can give us a healthy, long life span. Thus a healthy, long life span is not just dependent on proper food intake and exercises. It is a fact that despite eating proper food and exercising regularly, if our inner secret regions are not optimally balanced, it will make our body unhealthy and can lead to premature death too. The same holds true for our mental center. These 7 Chakras influence various levels of consciousness and the annihilation of the conscious and unconscious mind can be converted to uplifting of pure consciousness (soul). Spiritual practice based scriptures speak of attainment of Ridhi-Sidhis i.e. divine glories. But one can attain even greater benefits both materially and spiritually if one makes apt use of the storehouse of infinite energy present in our inner soul via scientific spiritual practices.
Life is a Yajna (sacred sacrifice). It is not merely as though offering worship materials to sacred fire is called Yajna. According to the level of the micro body and macro cosmos many small/big subtle Yajnas take place. The 7 Chakras are 7 sacrificial pyres of Yajnas. In the Yajna of Sadhana (spiritual practices) you have 7 fires, Purhoit of 7 Rishis, 7 demigods
