Remember, training depends upon circumstance and need. Master Zhao Ming Wang often addresses men (and women) who are around forty to fifty-years of age. This is the middle-age period of life when many different ailments and medical problems arise. To ‘purge’ the system of this lack of positive (yang) qi a training period of one hundred days of strict vegetarian diet and celibacy is required. At the end of this training – the practitioner – within a balanced reason, can revert back to ordinary life. As you have read, ‘inspiring’ sexual jing – but not expending sexual jing – is definitely a traditional method. Sometimes, couples participate within Qianfeng training and ‘inspire’ one another’s sexual jing whilst stopping just short of ‘emitting’ this precious and valuable substance. Now, preserving sexual jing is thought to ‘boost’ the entire living organism – but if your jing-levels are functioning within acceptable parameters and there is no general health deficiencies – then when engaging within sexual union with your partner – you can ‘absorb’ their sexual energy as the absorb yours.
