He was initiated into astrology by his late mother, K. Saraswati Devi, at the age of twelve in 1943. He regards her as the best astrologer he has known in two areas, marriage and children and prashna (horary).
More interested in games and sports than in astrology in his youth, Rao won brilliancy prizes in chess competitions and two state championships in bridge competitions. He played ten other games which is why in his astrological writings also there are references to games often.
His interactions with foreigners have been both on professional and astrological levels for more than two decades which is why he has, as an astrologer, a large international network of friends. He went on doing all his fundamental researches in astrology during his service career because of which, he went on collecting horoscopes systematically in thousands.
He has in his possession more than 50,000 horoscopes with ten important events of each individual noted with him.
Both his mantra guru, Swami Paramananda Saraswati, and his jyotish guru, Yogi Bhaskarananda, taught him some secrets of spiritual astrology which are not given usually in any book of astrology. Rao has revealed some of these secrets in his book, “Yogis, Destiny and the Wheel of Time”.
Among his recent fundamental and most original researches are his two books “Predicting through Jaimini’s Chara Dasha” and “Predicting through Karakamsha and Mandook Dasha”. It has been possible for him to produce such researches because he was told by his jyotish guru that what was in parampara (tradition) was much more than what was contained in books of astrology which are translated literally and are without illustrations generally.
