The great astrologer Sri B.V. Raman said about Kala-sarpa yoga: "Kala-sarpa Yoga has its bright shades. It [is said to] makes one industrious, hardworking, aware of one's own ability- despite mental restlessness. It raises the natives to top positions in their respective fields provided of course other Raja Yogas are present. Rahu-Ketu axis favors rise in mundane life while Ketu-Rahu axis indicates elevation in spiritual matters. It is also found that Kala-sarpa Yoga natives get betrayed by trusted friends and even relatives. Suffering due to developments in life strengthens the mind and mellows one's outlook. This is a blessing of Kala-sarpa Yoga." I agree with his opinion that a person seasoned with challenges in life can acquire the grit and effort and strive to overcome the obstacles and attain success and high achievements, as in the case of Pandit Jawaharlal Nehru. Ordinary persons may be crushed down by the malefic effects of Kala-sarpa-dosha; I saw such persons in my life. (1) A clerk in a college in Visakhapatnam; he was my neighbour; I saw his life during 1978—2002 period and how Kala-sarpa-dosha impeded his progress in all aspects of his life. (2) A distant relative ; I watched his life during the period 1967—2003 and how the kala-sarpa-dosha spoiled his life; his school carrer ended with 5th class (he was 15 years of age when he completed his 5th class); he spent the life of a vagabond and parasite; he always depended on his brothers and uncles and cousins for his livelihood. His wife left him 3 months after marriage; he had no family life; no progeny. === You can get my full particulars from my web-site : www.jyothishi.com.
