Cool if you can provide an example on how you would change your chart.
The chart reflects negative karma to varying degrees, so removing negative karma will help destroy negative elements. This also helps for bad behaviors/karma created after one's birth.
Pay attention to which planets are weakened, such as in weak signs, or aspects that are clashing or otherwise opposed. Also, look at Azazel's Astrology for bad degrees. You want to look at all your elements, and by extension all your zodiac symbols, and see where you may be weaker. Each house has a default sign as well, so looking at which houses have no planets or bad signs is another good start.
Maybe someone can make the case that an aspect with clashing energies can also be good, and perhaps this is true. However, these are more likely to be problem areas.
In addition, sometimes a planet may be "diluted" by a harmonious aspect. For example, Mars aspecting with Neptune energy may make their drive have less of a firey characteristic, and more intuitive or watery. In this case, one should keep the positive elements gained by Neptune, whilst bolstering the characteristics of Mars that might have been "diluted".
In the above example, a Mars square would suffice. In a general sense, Sun energy can be used to positively transmute aspects. In addition, any 40-day work you do on yourself, in general, like boosting intelligence, does improve your chart, since your chart is really just you.
One can also do a general working, if they are unable to decide on specifics. One would use sun energy and affirm it transmuting all aspects of one's personality to the highest expression. In a similar sense with negative karma, it is good that something is done, but if one has a major glaring issue, focused attention is better.
Moving on, one should read through the runes and look at qualities they may be missing. Each of the runes is based on an element or planet to some degree (or multiple), therefore there should be a rune for everything. Combine that rune with sowilo to boost it, then program it to positively change you.
-------------------------------
Lastly, don't forget general or "daily" balancing that takes the form of yoga, alternate nostril breathing, and working with ether. I view astrology as separate from one's current elemental balance. While it does set the stage for one's default elemental state, one can also balance their elements without a major working.
Astrology reflects almost the "skills" you developed from each of the elements, whereas the current elemental balance is just how you operate on a daily basis. Balancing oneself with ether will not make one lose their astrological traits, but it will set a better stage for them to develop the skills they are missing.
Someone with lots of fire would do well to make sure they have sufficient water in them. Someone with lots of air would need earth to help them develop better earth-like behaviors. That is where using ether daily can come into play, such as taking in 5 breaths and programming it to balance oneself.
---------------------------------
I rambled on longer than necessary. The actual premise and execution of this is much simpler than it sounds. The key thing is to be aware is that correction is actually necessary to do, especially with outright destructive aspects, awful karma, or lots of dirt/blockages. Continual empowering will just make it worse.
