An aspiring Yogi wanted to find a Guru. He went to an Ashram and his preceptor told him: You can stay here but we have one important rule - all students observe Mouna or vow of silence. You will be allowed to speak in 12 years. After practicing for 12 long years Yoga Asanas, Meditation, a lot of Karma Yoga, etc, the day came when the student could say his one thing or ask his one question. He said: "The bed is too hard." He kept going for another 12 years of hard Sadhana and austere discipline and got the opportunity to speak again. He said: "The food is not good." Twelve more years of hard work and he got to speak again. Here are his words after 36 years of practice: "I quit."His Guru quickly answered: "Good, all you have been doing anyway is complaining."
