文／蓮生活佛  盧勝彥

我個人發現一個小祕密，也就是一個密教行者修法之中，要先「觀空」，因為「觀空」很重要。只要你將自己心念停止，空了自己的想念，就在這恍惚恍惚的一剎那之間，宇宙意識的法流會灌頂入你的身心之中。
我個人的體會是這樣做的，我先想自己坐在八葉蓮花座上，而自己的面前有一光明的月輪。
我唸觀空咒（淨三業真言）：
「嗡。速八瓦。速達。洒爾瓦。達爾嘛。速八瓦。速朵。杭。」誦咒五遍。
將月輪愈想愈大，大至無盡。
我與淨月輪互相融入。
一切皆空。
就在這時候，光明法流入我的身心之中，充滿我的身心，馬上相應「八觸」：
一、動觸——身體起顫動。
二、癢觸——全身如蟲爬，有癢感。
三、輕觸——身輕如雲飛行。
四、重觸——身重如山，如如不動。
五、冷觸——身冷如水，清涼如冰。
六、暖觸——身熱如火，暖得舒適。
七、澀觸——身周如木板堅固。
八、滑觸——全身滑如脂。
所以，我如此說，只要修一壇法，就等於宇宙清淨法流給你灌頂一次，也就是你與法流相應，你融入法流之中，你和佛菩薩產生了對流，你和佛菩薩有了交通。
這「觀空」是瑜伽密教的第一個祕密了。

The Secret of Contemplating on Emptiness

　　I have discovered a little secret which highlights the importance of contemplating on emptiness before a Tantric practitioner begins his or her cultivation practice. As long as you still your thoughts and empty them, absorbed in this state for one split moment, the spiritual current from the Cosmic Consciousness shall empower you, flowing into your body and mind.
　　My personal experience on the procedure of this practice goes like this. I first imagine myself sitting on an eight-petalled lotus throne and a luminous moon disc appears before me. Following this, I recite the Contemplation of Emptiness Mantra (the Purification of Three karmas Mantra):
　　OM SOBHAWA SHUDDHA SARWA DHARMA SOBHAWA SHUDDHO HAM (Recite 5 times)
　　Visualize the moon disc expanding until it is immeasurably massive.
　　I am merged with the pure moon disc.
　　Everything becomes emptiness.
　　At this moment of emptiness, the spiritual light current flows into my body and mind, filling my being, which at once responds with the eight sensations:
　　A tinkling sensation - The body experiences a tinkling sensation.
　　An itchy sensation - It feels like having insects crawling all over one’s body, resulting in an itchy feeling.
　　A light sensation - The body feels as light as a moving cloud.
　　A heavy sensation - The body weighs like an immovable mountain.
　　A cold sensation - the body feels as cold as water, yet as refreshing as ice.
　　A warm sensation - The body feels like it is on fire, yet it is comfortably warm.
　　A rigid sensation - The body firms up like wooden planks.
　　A slippery sensation - The body feels as slippery as grease.
　　This is why, when I say that when you cultivate one session of practice, it is as good as receiving an empowerment from the pure spiritual current of the universe. This is tantamount to having a union with the spiritual current where you merge into it and kindle an exchange and interaction with the buddhas and bodhisattvas.
　　This Contemplation of Emptiness is the first secret of Yoga Tantra.
