In certain other aspects they differ from each other. For example the square opposition aspects are bad and trine and sextile aspects are always good in Western Astrology. Where as in the Hindu system good and bad aspects are not based on the types of aspects, but by the nature of the planets involved in the aspects. Ashtakavarga system, Shadvarga charts, Shadbala assessment and Yogavali are not found in the Western System.
The Indian Science of Astrology also gives certain remedial measures to overcome mental, moral and physical sufferings by means of medicinal roots, mantras and yoga practices and Gemstones. Though Hindu Astrology deals with all the aspects of human life indicating materialistic success and failures, it is deeply rooted in philosophy.
As i said in the beginning the very purpose of Astrology is to alert an individual about on coming events whether good or bad,provide insight into the behaviour of the members of the society and like a psychiatrist,provide counselling for the needy.(we will meet again)
