Ans. Each individual is born with certain characteristic traits and IQ., all of which can not be explained as genetic inheritance. For instance, genetics has no explanation for the rare birth of a saint, genius or an idiot in several generations of a family. It is also a fact that many of these exclusive personal traits change in course of growth of the person from childhood to adulthood. Modern scientists generally ascribe these changes to social environment and education . The science of today is, however, unable to throw light on the reasons for presence or absence in an individual of characteristics like empathy, compassion, large-heartedness , tolerance, courage, equanimity and creativity . Nor has modern science succeeded in devising gadgets or courses for inculcating these virtues. The spiritual masters in the East on the other hand, maintain that the Absolute Repository of all virtues, which we call as GOD , is that source from which it is possible to acquire positive traits by personal endeavor through specific Yogic exercises under the guidance of a Guru . This is the objective of all spiritual pursuits in the East. Ever since the dawn of civilization in India, it has been emphasized that no amount of material progress in science and technology can bring about lasting happiness, peace and prosperity for humankind, unless the individual - the unit of family, society, nation and global population, is transformed by infusion of positive thinking. The so-called progress in the West is also responsible for two world wars, nuclear-pro life ration, environment al pollution, disparity in living standards, conflicts, poverty and disease all-over the world. Gayatri is a panacea for all problems - Personal, Family, Social, National or Global : The Gayatri Sadhana is a product of thousands of years of research . Following Gayatri Yoga any individual, irrespective of caste, class, colour, nationality, social status and religious affiliation can acquire strength from the Indwelling Divinity for solving all problems of life .
