From the very beginning of his teachings, Yogi Bhajan instilled within his students and through his own personal practice the discipline of sadhana. The word actually means discipline and in this practice indicates a personal kriya or meditation commitment, or the complete Aquarian Sadhana which he outlined for the early morning hours, before the sun rises. In these lectures he describes his personal practice, the benefits of 40, 90 and 120 day practices, the teacher's sadhana, and the path from sadhana to aradhana to prabhupati – the path to enlightment.

从教导之初，Yogi Bhajan 就以自身的实修，把 sadhana 的纪律种进学生心里。这个词本身就是「纪律」的意思，在实修上指个人对某个奎亚或冥想的承诺，或是他为日出前的清晨所拟定的完整水瓶座 Sadhana。这些演讲里他谈到自己的实修、40 天、90 天与 120 天练习的益处、老师的 sadhana，以及从 sadhana 到 aradhana 再到 prabhupati 的道路——通往开悟之路。
