从张开的口中，阿字如箭般射向梵穴。专注于如弓满张般的空中，稍作收摄。由此，将生起无所思的殊胜三摩地。若觉知散乱和掉举，则专注于心间的红色阿字。半闭双眼，稍稍向下观视并禅修。若昏沉，则如前禅修，由此，将生起远离昏沉和掉举的无分别智慧，如河流般涌现。如是夜晚分三时段修持，将生起乐明无念的殊胜三摩地，并成就现观等功德。迅速解脱于无勤任运的普贤法界。在此，全知法王开示：如是日夜修持的一切时分，因闲暇难得，故当精进不使闲暇空过；因寿命无常，故当知修行不应拖延；因轮回是苦，故当对世间生起厌离；因诸法无自性，故当对任何事物皆不执着实有；因涅槃是至乐，故当修持寂静菩提；因密咒能以方便道成就，故当修学各种道；因大乘依赖于大悲心，故当具足利他菩提心；因加持依赖于信心，故当视上师为佛；因一切皆归于自心，故当修习无偏清净观；因轮回由错觉妄念所生，故当斩断能取所取的根本；因苦乐由业力所生，故当取舍善恶；因轮涅由觉性所显现，故当认识觉性的自性。以十二要点调伏自心，乃极重要的窍诀，当铭记于心。如是说。第二、关于旁述之义：思维以上所说的各种对境之必要和意义，以及身验、觉受等证相、程度，遣除违缘、增益，从体验生起次第到认识之方法等，皆于《铜书函》等根本口诀，及其释义《如意宝》中，以取舍的方式阐述而了悟。

From the opened mouth, the letter A shoots like an arrow towards the Brahma aperture. Focus on the sky, which is like a fully drawn bow, and practice holding back slightly. By doing so, a good samadhi of non-thought will arise. If awareness is scattered and agitated, then focus on the red A in the heart. Half-close your eyes, look slightly downward and meditate. If you become dull, then meditate as before, and thus, non-conceptual wisdom, free from dullness and agitation, will arise like a flowing river. In this way, practicing in three sessions at night will give rise to a good samadhi of bliss, clarity, and non-thought, and manifest realizations and other qualities will be accomplished. You will quickly be liberated into the realm of Samantabhadra, free from effort and action. Here, the Omniscient Dharma Lord said: "Thus, in all times of meditating day and night, because leisure is hard to find, one should strive not to let leisure be wasted; because death is impermanent, one should know that there is no time to delay practice; because samsara is suffering, one should develop renunciation towards existence; because all phenomena are without inherent existence, one should not cling to anything as real; because nirvana is supreme bliss, one should practice peaceful bodhi; because secret mantra is accomplished through skillful means, one should train on various paths; because the Great Vehicle relies on great compassion, one should possess the altruistic mind of bodhicitta; because blessings rely on faith and devotion, one should see the lama as the Buddha; because everything comes down to one's own mind, one should train in impartial pure perception; because samsara arises from delusion and false concepts, one should cut the root of grasping and fixation; because happiness and suffering arise from past karma, one should adopt and abandon good and evil; because samsara and nirvana arise from awareness, one should recognize the essence of awareness itself." Taming one's own mind with these twelve key points is a very important instruction, which should be contemplated from the heart. So it is said. Secondly, regarding the supplementary meaning: The necessity and meaning of meditating on the above-mentioned objects, the signs and degrees of physical and mental experiences, the removal of obstacles and enhancement, and the methods of recognizing the stages of experiential arising, etc., are all explained and understood in the root instructions such as the Copper Letter Box, and their commentaries, the Wish-Fulfilling Jewel, in the manner of adopting and abandoning.
