Here are some words from Tulku Urgyen Rinpoche about the Lotus Essence Tantra:
My guru uncle Samten Gyatso had many lay students and they all knew the Lotus Essence Tantra by heart. There wasn’t a single one of his students who didn’t know how to chant this tantra. Whenever they had a free moment or even while walking about they would recite it from memory. Many of his old students said that it was very good to chant because whoever hears it will be liberated. That is the kind of pure appreciation that they had.
There is a long version of Liberation Through Hearing called the Single Child of All Buddhas Tantra, which is a much longer text but still there were many of Samten Gyatso’s students who knew that by heart as well.
Samten Gyatso once said that, “I have two things through which I can benefit other beings, one is the Single Child of All Buddhas Tantra and the other is the Lotus Essence Tantra. And there is absolutely no doubt about that!” Normally he would never mention anything of the kind, he was what is called a ‘hidden yogi.’ He would never talk about himself as being anything special, not even a single word. He was never heard saying, “I have realized …” or “I am special. I have special qualities.” Not once. He would move around just as if he was a completely ordinary person. But he did say, “There truly are two things that I have which can benefit others. One is the Single Child of All Buddhas Tantra and the other is the Lotus Essence Tantra.”
