it can be a kind of "death before dying" experience, that results in a new stage of awareness along the enlightenment process, but let's be honest, there has got to be a way of going through that that is less traumatic and life-disruptive!
On energetic practices:
Qigong, Neigong and other practices can result in the over stimulation of the mind and lead to anxiety, and panic attacks, manic type euphoria, and sleep-deprivation induced hallucinations. The practitioner needs to be able to ground out this abundance of energy, or gather it up and store in in their lower dan tein.
Some methods on grounding are sitting on earth and feeling the energy being dumped into the earth. Slow deep breathing. Eating a heavy protein meal. Taking a luke warm shower as long as possible, and feeling the energy draining away. Getting a good restful sleep by taking melatonin, and chamomile before bed. Isolating themselves from others until the excess energies are gone from their system.
Please don't take this as an attack, really its just a rant against society.
On enlightenment:
A lot of people think enlightenment one of those things you can try out for the weekend but then go back to work on Monday at your 9-5, and then go bowling on Tuesday, and church on Sunday. We're really talking about fundamentally changing the way we view reality, a complete 180 in paradigm. That isn't something you can achieve and still remain exactly as you were. It's really not a "have your cake and eat it too" scenario.
Enlightenment is a completely new paradigm and mode of being or rather non-being, learning to adjust to it, while still acting normal and functioning according to your previous paradigm (while in the presence of others) isn't going to be easy.
I guess it all boils down to how you define enlightenment.
If you define enlightenment as an expansion of mind, self, ego and consciousness, or elevation to divine status, etc. Then yes there are better ways.
If you view enlightenment as permanent non-dual awareness, awakening from the dream, and the realization of truth, then no there isn't a better way. You can't keep yourself, your ego, your identity, your sense of self, and still be enlightened, Sure maybe you could keep your ego around as perhaps a costume used to interact with the rest of society out of necessity, but its not the same, there is no one behind it.

Everyone says they want the truth, but what if the truth isn't something they would like to hear. What if is scary, and leads to uncharted territory?
The Buddha said verbatim this world is a dream, and we are all asleep. To wake up you must first realize the life your living is a dream. Not many people are willing to do that.
Sometimes people have so called "psychotic" reactions to glimpses of truth, they have as a result of their meditation. 10 minutes of true non-dual awareness would be enough to send most people I know into a serious existential crisis. But that isn't such a bad thing,that is if they really want the truth.
What if the truth means the life they have been living wasn't/isn't real, and the ego and identity they had built up was no more real than a fictional character in a dream.
That just isn't something people want to hear, or much less think about, truth or not. They want something which will make them feel good about themselves, give them purpose and meaning, within the context of what they currently believe to be real. Truth isn't what most people are after, they really want sleeping pills.
If truth and enlightenment are truly what someone seeks, then a so called existential crisis, or "psychotic" break might just be the best thing to ever happen to them.
Rant on psychosis:
Modern day psychiatry is a sham. Any person who belongs to a non-mainstream belief system or lack thereof, runs the risk of being diagnosed with a disorder or illness. Despite the fact this runs completely against the founding principals of our constitution, it is common place and accepted in our society.
Every day across the world, thousands of people that pose no threat to themselves or others, and are perfectly capable of functioning in society are imprisoned and drugged until they are deemed "well". This diagnosis is made by individuals who practice not an objective science, but an art.
There are many people who have been committed for espousing the teachings of the Buddha as actual realizations they themselves had, or in a literal belief (not intellectual) in pantheism, nihilism, nondualism, shamanism or a myriad of other religious or philosophical ideas and concepts. They're incarcerated and drugged, and lost in a legal limbo for the rest of their lives if they don't pretend to "get well".
Some people who refuse to admit their "insanity" are given shock treatments, and strait jacketed in padded rooms. The lobotomy is still a practiced procedure, although now it hides behind the term "psycho-surgery". The long term effects of some of these medicines are horrible, renal failure, Parkinson's, diabetes, and some are extremely neurotoxic.
I am not sure modern day psychiatry is any better than it was in the dark ages, when we preformed trepanation to release the demons from peoples heads.
A persons sanity should only come into question if they are unable to function in society and abide by its laws, and rules, or if they pose a threat to themselves or other people. Unfortunately that isn't the case.
