Yoga Science is an ancient Indian discipline that traces its roots back five thousand years to the Vedas, a collection of texts authored by Vedvyas during the Treta Yuga. The essence of Yoga is elucidated within these sacred scriptures, which form part of the Sanatana Dharma and encompass the 4 Vedas, 18 Puranas, and 108 Upanishads. Within the Vedic teachings, the definition of Yoga is expounded. Furthermore, the Yoga Sutras of Maharishi Patanjali, known as Raja Yoga or Ashtanga Yoga, outline the principles of leading a righteous life. These sutras encompass eight limbs enables the awakening of mudras, bandhas, and chakras within the physical body, leading to various health benefits.

From the mythological period till today, the practice of worship and worshiping God with dedication and consciousness, along with the use of herbs to remove any ill-health or incurable diseases, is going on as a general activities in the Indian Public domain. Have we tried to know carefully on this- whether it gives only satisfaction to the mind or does it have any scientific basis? In this connection, i). what are the benefits of the transfer of energy in the physical body and the energy generated from it (aura), ii). what remains effective in some area, other than the body, iv).what is called pranic energy and v). what are its benefits, has been mentioned in the book.

Yoga is a five thousands year old style of Indian wisdom and is the science of living. Maharishi Patanjali originated Yogasutra from the Sanskrit word YUJ, means to combine or unify each other. He described the yoga as Rajyoga or Ashtangayoga. Yoga consists of eight organs: (i) Yama, (ii) Niyam, (iii) Asana, (iv) Pranayamas, (v) Pratyahara, (vi) Dharana, (vii) Dhyana and (viii) Samadhi. Many people consider illusionism yoga to be only a physical exercise, and adopt a complex way of stretching and breathing exercises of the body, but with performing yogasanas, panayamas and meditation, the body remains perfectly healthy. Patanjali's Yogasutra focussed on finding simple but profound yoga principles (Yama and Niyam), which can become the essence of a happy and healthy life for us. The 'contentment' principle (Niyam) helps in being satisfied in life and 'imperfection' theory in relieving anxiety, distraction and stress due to greed and attachment. The 'defection' principle describes mental and physical purification. These rules especially help us when we are worried and adopting the scientific methods, to make life more meaningful for serving the public at large.

योग दर्शन मुख्यतः दो अस्तित्वो के समन्वय का शाब्दिक अर्थ है और योग शब्द के भी दो अर्थ हैं पहला संयुक्त और दूसरा समाधि। इसकी उद्भूति ईसा पूर्व दूसरी शताब्दी में महर्षि पतंजलि के योगसूत्र से हुयी एवं उत्पत्ति संस्कृत के मूल शब्द युज (YUJA) से हुयी है। युज का अर्थ है - एक दूसरे को मिलाना या एकजुट करना । महर्षि पतं]जलि के योग को राजयोग या अष्टांग योग कहा जाता है। उक्त आठ अंगों (1)यम (2)नियम (3)आसन (4)प्राणायाम (5)प्रत्याहार (6)धारणा (7)ध्यान (8) समाधि में ही सभी तरह के योग का समावेश हो जाता है । मानव भौतिक अनुप्रयोग और यौगिक ध्यान के तकनीकों का उपयोग करके मुक्ति प्राप्त कर सकता है, और इस प्रकार मनुष्य प्रकृति से अलग हो जाता है । परन्तु जब तक आप अपने को खुद से नहीं जोड़ेंगे, समाधि तक पहुंचना मुश्किल होगा। प्राचीन योग, हमें ज्ञान को जानना और प्रयोग करना, सरल अपितु गहन योग सिद्धांतों (यम और नियम) के बारे में बताता है, जो हमारे लिए एक खुशहाल एवं स्वस्थ जीवन का सार बन सकता है। 'संतोष' सिद्धांत (नियम) जीवन में तृप्त रहने के तथा 'अपरिग्रह' सिद्धांत लालच एवं आसक्ति भावना से होने वाली चिंता, व्याकुलता एवं तनाव से मुक्त करने में मदद करता है। 'शौच' सिद्धांत मानसिक एवं शारीरिक शुद्धि के बारे में बताता है। यह नियम विशेष रूप से आपकी तब सहायता करता है जब आपको संक्रामक रोगों से पीड़ित हो जाने के डर से व्याकुलता हो ।

The vibration of Heat Exchange Tubes due to hydrodynamic fluid coupling is an international problem for Nuclear fuel assemblies etc. on account of frequent failure of Heat exchanger tube, which causes not only expensive repair but a great loss to the plant. Thus, several studies in this field have been made so far. But here, a study of three circular cylindrical tubes in a liquid is done on the analytical approach. The author also describes the various parameters for maximum efficiency of heat transmission from Heat Exchanger's, which is defined as; nH =F (G/R, V) = Heat transmission efficiency of the heat exchanger, where G=gap between two adjoining tubes, R= Radius of cylindrical tubes (if considered of same diameters) and V= fluid flow velocity and geometry of tubes. The relations amongst the above parameters are yet to derive to solve this problem.
