Astrologer and proficiency in astrology

The proficiency in astrology is the ability to depict the future events according to the configuration of planets at the time of birth. Dasa system is also one such method. There is reign of a planet in its Mahadasa (main period) according to the nature, characteristics and strength of the planet and events happen accordingly. In Ram rajya the public feels secure, prosperous and there is justice in day to day matters. In ravana rajya there is injustice, anarchy and chaos everywhere. To summarise, joys and sorrows are experienced according to the dasa at that time.
According to Astrologer Hemant Sharma ji the in horoscope reading Astottari, Yogini and Kala-chakra dasas are used by the rank and file of astrologer; but Vimsottari dasa is widely accepted one.
Vimsottari dasa is the supreme in kaliyuga.
The benefic and malefic nature of planets, their auspicious or inauspicious placements and their strengths decide whether the events signified by them will be good or bad, are good or bad or had been good or bad. It is like the shape, size and fruits of a tree depending on the seed (quality) that was sown for that tree. The deeds of the previous births are the seeds of the life tree of this birth and the prosperity or adversity that has to be experienced in the birth by the native depends on the quality of seed the native has inherited due to good or bad deeds done in the previous births.
Vimsottari dasa system of timing of events is the most prevalent system now a days the world over. In India Vimsottari dasa is mentioned most essentially in birth chart though other dasas are also some times given as an additional advantage.“ The principle of Vimsottari dasa are very near to the perfection say the learned” in astrology. Even the results given in famous ‘Bhrigu-Samhita’ are based on the Vimsottari dasa Paddhati (system) for timing the events.
The Nadi works of south India like ‘Bhrigu-Nandi Nadi’, ‘Chandra Kala Nadi’ (Dev Keralam) Sapta Rishi Nadi’ etc have used Vimsottari dasa system for nativitivities mentioned therein. The authors like Varsha Mihira, Satyacharya own reasons. These authors have used some other dasa system which is not prevalent now a day and no author or practitioner now a day uses that dasa system perhaps due to its inefficacy.
