I practice what is referred to as the water tradition, a very internal cultivative practice. There is no enlightenment at the end of the road. In fact, there is no end of the road. Physically, I practice Chen-style Tai Chi and do some Qi-Gong breathing daily. I've just started exploring Hsing-I. My meditations are typically either exploring emptiness beyond my mind, or feeling the chi move through its pathways. I have circulated the microcosmic orbit, and have gotten as far as opening the second circuit or gate. I've got a long way to work with that though. One of my most significant early meditative experiences was when I was focusing on the center of myself, passively observing my thoughts. After maybe a half hour, I felt a pressure at the top of my head and I could see a whirlpool within myself. I was being pulled in, but I wasn't scared and somehow knew nothingness existed at the bottom. Before I could get there, something pulled me out.
I generally follow the dietetics practices whereby I stay away from all preservatives and processed food, eat fresh fruit and vegetables, stay away from most grains and most meat. This, in combination with pathway healing meditations (whereby you carefully sweep your meridians for blockages) is very energizing. Understanding how the 5 elements work within myself has saved a lot of doctor appointments for little issues. One acupuncture session resolved a problem doctors couldn't even identify for nearly 4 months. What you think about is just as important as what you eat and drink. In that regard, I stay away from television but not movies. One of my favorites is "Spring, Summer, Autumn, Winter and Spring", a Korean film. More recently I tend to use Hollywood's emotional choke-chains to explore my own emotional triggers.
Physical immortality doesn't, in my opinion, mesh well with Taoist belief because it's an extreme and I suspect there's been some misinterpretation over time. I do think we can live "a lot" longer than we are now, but physical immortality is not possible. Death of the body is a necessary experience, but you can generally control when that happens. I believe your spirit returns to the Source when your body dies and a necessary goal of your practice is to prepare your spirit for that eventuality. Eating and drinking well, thinking not negatively (but not necessarily thinking all positively), and enriching your energy will provide your body with a long life in which to cultivate.
I don't follow sexual alchemy. I've read extensively about it, but haven't dove in.
There's two sides to the I Ching. One side is knowing generally what's happening in each hexagram, associated trigrams and lines. The other side is how you relate to that and can work through inauspicious circumstances. The first side can definitely be understood by anyone. By knowing it, you can say to yourself, "what's happening now is much like hexagram 'w', and since I know the lines move like 'x', I bet 'y' is going to happen, so I'll do 'z'." That's the macro. The micro is applying that to yourself, identifying hexagrams, trigrams and moving lines to your own circumstances. Being able to deal with that is a matter of ego -- your ego isn't willing to admit you screwed up or it'll place you on a pedestal if you've done the correct thing. Sometimes the correct action is to do something most people don't want, but you have to accept maybe a tornado is necessary "because" of the damage. Accepting and acting on what the I Ching means personally, "good" and "bad", is what those Masters are saying; that cannot be done until you're ready.
Everyone here can agree that once you've opened yourself you can begin more easily identifying opportunity. One particularly important Taoist practice is helping others (partially for the purpose building your own virtue). This was so refined that they actually had points for each action, with the goal of getting to the next level. Now, I don't count points, but the intention is interesting. I've found the more I grow the more I find opportunities to help others, be that just listening to actually physically enabling. The more you give, the more you get.
What I get most out of the religious practice is the idea that ritual strengthens habit. Building those habits is very important when living in our culture. Most chants are foundational text, which are good to memorize. When you kneel, who are you worshiping? Perhaps yourself? As for worshiping Gods and such, I think that's bull and nothing more than a hold-over from ancient times. However, the statuette of Kuan Kung on my work desk is a nice symbolic reminder
(Read the "Romance of the Three Kingdoms" to learn more.)
My views about religion overall is an internal conflict because I was raised a church-going Protestant and voluntarily separated myself from that, going first to atheism, objectivism -- then after a brief stint with Buddhism and a "crisis of faith", found the Tao. If you study the history of Taoism, you'll find that the more popular aspects of it weren't Taoist in the first place -- they were later adopted. The greatest periods of Taoism expansion coincided with equal religious development. The two are intimately intertwined and cannot be separated. Despite this, I distinguish the cultural context from the core intentions. Much of the pomp came from reactions to Buddhism, which was as symbolic as Taoism was not. Take out the pomp and the god worship and you've got something quite powerful. Conversely, you cannot place too much importance in it because ultimately acceptance and the cultivation has to happen internally, but the filtered dogma and ritual certainly helps buttress it.
