Lu-2 Yun Men 云门 Cloud gate

Lu-2 YúnMén 云门 Cloud gate

Lu-2 YúnMén 云门 Cloud gate

【Name explanation】1) 云, Yún means cloud; 门, Mén means gate. Earth Qi vapourizes up to form clouds, hand TaiYin channel Qi is formed by the earth Qi (food and grains) from the center burner that vapourizes up and gathers at Lu-1(中府) and exits at Lu-2 to spread in the twelve channels. Like clouds gathers in the sky to spread rain under the heavens, therefor it is called “cloud gate”.

2) Clouds are formed by heavenly Qi, heavenly Qi passes through the lungs(see 《Plain Questions 5, Great Treatise on the Correspondences and Manifestations of Yin and Yang》). Lu-2(云门), the gate where clouds passes, means that Lung Qi passes here. 《锦囊秘录》: “Mans Qi and blood, circulates without ceasing, starts in the hand Tai Yin, exits at Lu-2(云门), returns to the foot Jue Yin liver channel, enters at Liv-14(期门). ”

3) 云, Yún here means mist; 门, Mén means gate. Clouds are formed by heavenly Qi, heavenly Qi passes through the lungs. The upper burner is like a mist, when clouds get cold they fall as rain, when they get warm they rise and spread. Lu-2 is where hand Tai Yin Lung channel Qi exits, in the anterior chest region. From the upper burner Lung Qi interior, it is the gate where Lung Qi exits to the exterior, therefor it is called the Cloud Gate.
