I was introduced to this system known as the Genekeys (www.genekeys.com) a while back and found it very useful. There was a bit of an intellectual hurdle because my ego did not at the time "believe" in anything resembling astrology, but after testing this system out on countless of people the accuracy was enough to dispel that particular ignorance.

It is based on I Ching and Human Design (two other systems I recommend) and one of the things it does is map out the siddhis that (apparently) come pre-programmed with every individual incarnation. In this system there are 64 different siddhis, with corresponding gifts (apparent talents in the relative world) and shadows (apparent drawbacks in the relative world). According to this, you will be born with certain latent siddhis or abilities that will awaken as you develop on the spiritual path, but unlike many Buddhist traditions it encourages the development or insight into these as a part of your awakening, not as a distraction from it.

As an example I have the siddhi of "Empathy" in a prominent position in my chart, and can confirm that it is active. This allows me to feel fairly accurately what "others" are feeling as soon as I connect with them, assuming they are somewhat open. I've been playing around and investigating this a lot over the last few months and it seems to be an ability that many can develop, to a greater or lesser extent, but that your aptitude for it will vary. It would be interesting to see if those here who are interested in awakening or developing siddhis will have the same result, so hopefully a few of you will check this out.

Namaste
