If the mind is free from scattered thoughts, the scattered mind is eliminated; without a scattered mind, concentration naturally manifests. Scattered thoughts are the habitual tendencies of the manas (intellect) clinging to objects, which are difficult to overcome. One must find a way to subdue it. How can we effectively subdue the habitual tendencies of the manas? Seize upon its characteristic: it fears idleness and having nothing to do. Therefore, assign it a meaningful task, let it focus primarily on this activity, and convince it that this matter is extremely important. Once it recognizes the importance, it will inevitably concentrate its energy on this task.
What kind of task is most meaningful? Instruct it to recite mantras, sutras, or the Buddha's name. Initially, set a fixed quantity and duration. Once it forms a habit, there will be no need to specify quantity or time anymore. It will automatically and consciously recite mantras, sutras, or the Buddha's name, maintaining this state even during sleep. Thus, the power of concentration is cultivated.
The energy of the manas is too abundant; find a way to capture its attention and focus its energy. This depends on how the consciousness persuades the manas and how it arouses the manas's interest.
In daily life, whatever one is doing, one should mentally recite the Shurangama Mantra. Do not seek a specific quantity; its blessing power is immense. Strive to seize every moment to cultivate concentration. Once concentration improves somewhat, contemplate the five aggregates and the eighteen elements of perception. Begin contemplative analysis from the impermanence and non-self of the physical body. In the very moment the five aggregates are active, distinguish what the physical body is, what the aggregate of feeling is, which perceptions belong to which consciousness, what the aggregate of perception is, which thoughts belong to which consciousness, what the aggregate of mental formations is, and which volitions belong to which consciousness. Examine what the six sense faculties are, what the six sense objects are, what the six consciousnesses are doing, and then observe the arising, ceasing, and changing conditions of these dharmas.
