That really depends. Some of those methods work well for some people and not for others.
Since we're laying it out on the table, I'll comment on here about those different methods.
You won't be using the "Kundali" method (which I take it to mean "Kundalini"). That is a phenomena that is initiates a drastic transformation on the person's body and mind, and has its own way with the person. It may be induced and people can spontaneously have it kicked off.
People usually come for treatments for side-effects from that sort of spiritual emergence, and those side-effects are often knots of resistance in the mind or body.
Aura usually refers to a layer of subtle energy closer to the surface, and as such, something that as deeply transformative as Kundalini is overkill.
I can say the same about Ayahuasca. She is going to have her way with you.
Now, let's look at "chi isn't flowing correctly" and "it appears in the aura" -- which in the TCM modality would be the wei-qi, the guardian qi. The modern TCM practitioners will look at different physical symptoms and try to adjust things through acupuncture, acupressure, etc.
However, there is a smaller subset of TCM practitioners who can directly sense the flows of the qi. For those people, Metal qi feels like Metal, and it is distinct from Earth qi or Fire qi. Meridians for these people can be directly sensed within one's body and in others, and they more or less follow the pathways already documented. Through a combination of learned knowledge and intuition, there are some adjustments that can be made there.
That's not the only way. Specific qigong movements can affect specific meridians, and a specific set of qigong can be prescribed for someone to bring that person back to health.
Copper bracelet and healing crystals can have some effect. For people who can sense how those energies flow, they can tell what kind of effects that might have. (Note that not everyone is going to be able to sense in the same "spectrum"). It isn't just copper -- metal in general will change flows, and different types of metal will change them in different ways. The same with crystals. Someone who can sense these things and extract information can note the different "flavor" or "personality" of individual crystals of the same material, and that can affect someone.
I have not experimented much with aromatherapy.
Traditional cognitive therapy is interesting, and they can have an effect on people at the subtle energy level as well. That shouldn't be surprising as memory and cognition will take place in the subtle as well as the physical. It is possible that experiencing an insight in cognitive therapy will also unlock a knot in the subtle -- but it could happen the other way as well, where the loosening of the the subtle and physical body loosens up the mind enough for an insight (and attitude and behavioral changes) to emerge.
