A retrograde Atmakaraka indicates a deep-rooted desire as being the cause of the birth. This has to be seen from the nature of the planet which becomes the AK. For example, if Mars is AK and retrograde, then there is a very strong desire related to succeeding in some battle or competition in this planet and the native will be dragged into innumerable fights and will be fighting all the time. The solution lies in finding the best self-defense strategies based on Karakamsa of which, Ahimsa is the greatest. Similarly, if Saturn is the retrograde AK then the desire would manifest in the native doing something related to the elders or old knowledge in new bottles. When retrograde, this desire is very strong and will be the cause of all direction in life. The other signification of Saturn is sorrow and if the native gives sorrow to others, especially elders and those who are like Guru, then know that he is running a bad time and a lot of sorrow is in his destiny (in any case). The best remedy for him would be to develop a stoic attitude towards the acts and words of others and keep prodding in his path. In this manner, the retrogression is to be understood.
