When it comes to communicating in short range wirelessly, the blue tooth headset makes cell phone use a breeze. Technologically, the blue tooth headset is one of the most complicated and challenging of designs. They promote lightweight communication methods, with a battery and receiver built right into the ear piece. As complicated as they are to create, they are extremely popular for cell phone users everywhere.

Today, when you think of headset, you typically think of those that are extremely small and light to carry. What is great about blue tooth headsets is that they are wireless an, but not so small. What is happening is that there is so much to fit into the ear piece, such as receiver and transmitter, that they are having a difficult time trying to fit that much equipment into a tiny space.

Never fear technology advances each day and blue tooth is working around their obstacles. Consumers demand small and lightweight, blue tooth is working heavily to produce just that. To some people, even though blue tooth headsets are wireless, they tend to weigh slightly more which is considered to be a disadvantage to the technology and the headset.

Traditional headsets, with wires, when combined with cell phones did not present much of a problem when it comes to batteries, because they are wired. However, the problem with the blue tooth headset is that it is wireless and contains a battery within the headset. The problem is that the headset only lasts about twenty six hours when not in use and only 2 to 3 hours when talking. Manufacturers are developing ideas to keep the headsets usable for the maximum amount of time. This might mean turning off the headset after calls or having to connect the headset with each call.

Yet another disadvantage of the blue tooth headset is the range of calls. With blue tooth technology even though wireless, you cannot be far from the cell phone, not much further than the backset of your car, and still communicate. Therefore, it is still necessary to keep the phone with you at all times, even though it is meant to be wireless and hands free.

The Taoist world-view, and its associated yoga/qigong practices, is based largely upon an understanding of the flow of energy, within and outside of the human body, and includes an understanding of sexual energy which is far more sophisticated than anything produced by western culture. Integral to this understanding are what are known as The Three Treasures. These Three Treasures represent three types (or vibratory frequencies) of energy found in the human body: (1) Jing, or generative energy, (2) Qi, or life-force energy, and (3) Shen, or spiritual energy. Fundamental to all qigong/Taoist yoga practice, including sexual/consort practices, is the waking up of Jing/generative energy and its subsequent transformation into Qi/life-force energy and Shen/spiritual energy. And then, conversely, the transformation of Shen into Qi into Jing. In other words, the Taoist practitioner cultivates the capacity to circulate energy freely between its various forms/frequencies: from the most primal/mundane to the most refined/ephemeral and back again!

How exactly this happens is the subject of a vast field of enquiry & practice called Internal Alchemy. If youre interested in reading about internal alchemy via classical Taoist texts, please see Eva Wongs translations (from the Chinese into English): Harmonizing Yin and Yang, and Holding Yin, Embracing Yang. For a wonderful presentation of a sequence of qigong practices (which include sexual practices), please check out Eric Yudeloves book Taoist Yoga and Sexual Energy. In this and subsequent postings, Ill be introducing some of these (and related) practices, but theyre best done in the kind of long sequence that Eric Yudelove lays out and/or with the guidance of a flesh-and-blood teacher.

Heres a simple practice that you can try: sit at the very edge of a firm straight-backed chair (a wooden kitchen chair is ideal), with your feet on the floor and your knees directly above your heels. Your sitting bones should be firmly planted on the chair, at the same time as most of the length of your thighs extends out in front of it. Place your hands, palms down, on the front of your thighs, in a way that allows your shoulders to be relaxed, and let your belly be soft. Take a couple of deep breaths, letting go of any tension you find in your face, jaw, or neck/throat. Smile gently. Then, as you exhale, hinge forward at your hips, bringing your head down toward the space between your knees. With the very next inhale, reverse the process so youre once again sitting up-right. And repeat: exhale~down, inhale~up (like a crane, taking sips of water from a lake) Do your best, with each forward rotation, to rest the entire front-side of your torso onto the front of your thighs. Continue for a minute or two, then pause again in the upright position, and notice how you feel.

The second part of the practice is done entirely from the upright position (still sitting right at the edge of the chair, with your feet planted firmly on the ground). It involves coordinating the movement of your breath with the movement of your attention. As you inhale, feel your sitting bones becoming more heavy, releasing more completely into the chair. (You can imagine that your sitting bones are two heavy diamonds, which youre going to return to their home in the center of the earth.) As you exhale, feel a spaciousness, expansion & gentle effervescence at the center of your heart-space (that place behind the sternum/breastbone and in front of the thoracic spine). And repeat: inhale~sitting-bones heavy, exhale~heart-center spacious Continue for a minute or two, then pause, and notice how you feel.

This simple practice, if done regularly, has the power to wake up fields of sensation which are quite interesting, and enjoyable And can serve as a ground for the continuing cultivation of Jing, Qi & Shen: the Three Treasures which ~ from the point of view of Taoism ~ are the key ingredients of a healthy sexuality, among many other things
