first steps in advanced weigong
Once you have practiced qigong for a while (usually 6 to 12 months) and developed the ability to feel qi (as a palpable sensation which could be like pressure, temperature, tingling or some other somatic form) it's important for you to begin working at a deeper level which encompasses both the outside and inside of the body. The most important qi practices now are:
Sole breathing
Palm breathing
Top of the head breathing
As well, certain respiratory patterns (akin to pranayama exercises in hatha yoga) need to be incorporated. The most vital ones to start with are:
Normal abdominal breathing
Reverse abdominal breathing
You first learn these skills individually and then gradually craft them into groupings which dramatically increase your ability to sense and control qi.
lagna — the second hurdle to light
Once you start to align your lifestyle and actions with your authentic self (your deepest feelings and ethics), it's time to begin the process of tying in qi (prana or energy) to these truer expressions of heart and mind. In Jyotish, this corresponds to linking the harmonics you have created for the AL (arudha lagna) into the natal (birth) chart. The equivalent of the AL in the natal chart is the udaya lagna, which is usually just called the lagna. Udaya refers to the Sun rising in the east so the lagna simply indicates the direction where the Sun would rise on the eastern horizon at the moment a person is born.
The lagna represents an individual incarnating into this world, just as the Sun (soul) rises in the east (enters this world).
