The mainstream martial arts crowd know Qigong as a soft interal side of Chinese physical culture, in contrast to hard Hung Gar and Shaolin Kung Fu. However, Qigong is actually a good form of entry level training for serious Kung Fu cultivators. Its physically manageable movements and the focus on developing internal structure makes it good for beginners to learn the ropes while improving their body constitution.
Most people attach emotions to qigong. The emotions they carry in their heart while doing qigong depends on their personal philosophy, and for some, religion. For me, I carry courage and power in my heart. Courage and power is my philosophy. Qigong's purpose is to help people who're physically weaker to start with, to become stronger.
The way I do it, with courage and power in mind, is in line with ancient doctrine. I always tell students, qigong will give you noticeable benefits only if you can manifest a huge capacity and intensity of chi. If you feel a bit of involuntary movement in fingers or some tingling, it is a good start but it is not enough.
Always bear in mind the aim of Qigong, to become stronger, healthier and more energetic. You want to heal injuries with qigong, protect yourself from mild infections with qigong, you want to get from lethargic to energetic from qigong, you want to have stronger muscles and joints with qigong, and that realistically means becoming bigger, which is also legitimately hypertrophy!
It is not good to attach racial preferences or tendencies to our qigong cultivation. Like 'Chinese need a humble body with thin arms and a small family man belly', 'Westerners focus too much on arm and shoulder size and strength, they'll get the consequences of such sport training when they're old'. Such notions are not a healthy start for qigong. In qigong, we're all made of chi regardless of race or nationality.
What we tend to see, are qigong practitioners who think about 'love', 'kindness', 'happiness through forgiveness', 'let go of attachments'... well that' their philosophy. From what I see, it's very hard for them to manifest the positive warm and strong energy to empower themselves and perhaps transform their bodies.
Love and kindness without power will not improve your body. The chi in your body should be founded on courage and power. A worse situation will be the avoidance of courage and power, like it is harmful and evil. You're rejecting positive energy and being alive and kicking is a miracle of the power of life itself! That's bound to backfire. If you want to be healthy till old age, of course you have to embrace the power of life!
Of course, we should not reject 'love and kindness' too. We must always bear in mind that power and courage is the foundation and the grounding to develop 'love and kindness'. You can't develop 'love and kindness' on emptiness and a body with weak chi right? Power and courage are basics that should not be skipped.
When you return to the starting point of learning Qigong, what is the purpose? To make your body stronger right? Because health and energy is the core purpose and focus of Qigong, it's impractical and erroneous to get distracted by the temptation to 'love and care' for another person, and get completely veered off course, that the body improvement part has become secondary or even out of the picture.
Few people have a perfect body; people can only help others effectively when they themselves have health and energy. If you became healthy through practicing Qigong, you can introduce less healthy people to Qigong. From there, they need to be able to accept Qigong and stay on track with the practice if they want to help themselves.
