This Book deals in detail with the metaphysical concept of the various Fundamental Elements and Character Traits of this creation as they are explained in the Upanishads. These Elements are called the 'Tatvas', and the Character Traits are known as the 'Gunas'.

The 'Elements' or the Tatvas serve as the building block of the entire universe which is infinitely vast and multifarious in dimensions, while its character and nature as a whole, as well as that of its individual units, are determined by the 'Gunas'.

The Upanishads, which are singularly excellent repositories of metaphysical knowledge, have dealt with these twin concepts of 'Tatva' and 'Guna', i.e. the 'fundamental elements' and 'the character traits' of creation respectively, in fine detail.

In our Book we will be reading about the different types of Tatvas and Gunas, about their many variations and connotations, how they determine the nature and character of this vast and multifarious Creation by the virtue of their being its basic building blocks, and many other fascinating things pertaining to them as enunciated in the different Upanishads that deal with these two esoteric metaphysical principles. This Book will therefore enable us to get a comprehensive and an authentic idea of what constitutes the Tatvas and the Gunas.
