The intellectual history of mankind admits that man is the principal figure and that the earth on which he lives is the centre of the universe is wholly in tune with the crystallized concept of microcosm and macrocosm. Such a human is inclined to accept that his life is influenced by the components of the Universe, of stars and planets termed Astrology. The famous Astronomer-cum-Astrologer Varahamihira pays extraordinary compliments to a worthy Astrologer who, in his view, should know practically all branches of knowledge under the Sun, and be a guide, philosopher, and teacher of society. Every individual is psychologically interested and inclined to know his destiny of fortune and seeks the help of Astrology as a foreteller in the form of a personal consultation or through books on Astrology authored by valuable personalities. This book titled ‘Thithi, Yogi, and Karana’ is Unique as it has been presented in an elaborate form covering all essentials including ‘Indu Lagna’ and ‘Zero Sign’ with illustrations including ‘Yogi’ and ‘Ava Yogi (Evil monger). It is needless to say the reader can never find a book equivalent to this which has covered all the five limbs ‘Pancha anga’ interlaced with ‘Yogi’ ‘Ava-Yogi’, Indu Lagna and Zero Signs (Dagdha Rashis) the subjects that were never so elaborately dealt by any other author than Guruji Tirupur S. Gopalakrishnan who has more than 60 book titles to his credit.
