Several questions came up this evening about using the inner spheres of Dhamma and the power of mind.

The inner brightness already exists — you just need confidence and know-how

Someone asked: I can see a clear, bright sphere inside myself, but the space around it is dark, like a bright dot sitting in a dark room. Could Dhammakaya practice be used to clear that darkness away, the way flipping a light switch does?

The teacher answered: yes, but only for a brief period. He recalled a story Luang Pu once told, about a devout visitor from India who came to learn Dhamma and asked to be brought to the point of seeing brightness. Luang Pu set the condition that the visitor could not get up until he reached it. The man sat for many hours, enduring severe pain, and eventually did reach the brightness — but this method demands an extraordinary degree of endurance that most people simply don't have.

The teacher pointed out that, in truth, this inner sphere of Dhamma already exists within everyone — there's no need to wait to "see" it before using it. All that's needed is confidence that the sphere within is already bright; once you feel confident, that is already equivalent to brightness in your felt experience. Hold onto that feeling, and the visible brightness will gradually appear on its own. It's like a blind person living in the world: they can use a refrigerator, a car, a road, just as a sighted person does — they simply need someone to teach them how. The teacher noted that someone whose mind is still "blind" but who has been well taught and knows how to use what they have to good effect is, in fact, more admirable than someone who has already reached the brightness but doesn't value it and never puts it to use — because knowing without using is no different from not having it at all. The spheres of precepts, concentration, wisdom, release, and knowledge-of-release are all tools that already exist within us, each with a different role; we need to learn and understand them, then actually put them to use, in order to raise the quality of our lives toward purity and liberation.

Using these inner spheres to real benefit requires ripening the five spiritual faculties — mindfulness, faith, wisdom, concentration, and effort — to build mastery over oneself. Ordinarily, the unwholesome and neutral natures can control us at will, precisely because we lack this self-mastery. The method is to simply know, continuously, without thinking and without lapsing, so that the faculty of knowing — mindfulness — arises and draws in pure energy to clear away the defilement of ignorance. When all five factors are complete, they are called the Five Faculties, which then develop into the Five Powers — the strength that carries us to success at each level we aim for.

What is the power of mind, and how is it trained?

Someone asked what the power of mind is and how to use it, quoting the teaching of a senior revered teacher: "If you want power, you must bind your mind to one who has power — hold the same state of mind as they do, and your own mind will gain power over time; whatever you think of will come true easily. Most people have no power of mind because their mind is bound to those without power — to people, animals, or objects still heavy with defilement — which leaves the mind scattered and without strength."

The teacher confirmed this and explained that power comes in two levels. The first is connecting with teachers who have already mastered a particular skill but are still cycling through birth and death, mostly residing in the Tavatimsa heaven, known as vidyādhara. When a student needs to use that skill, they recall the teacher and invite the teacher's help, and the teacher assists by performing the technique for them. The second level is connecting directly with the true owner of the knowledge — the Dhamma body at its various levels — which requires daily refinement of practice until you can tune in to that inner knowing, at which point it transmits the knowledge to you, much like downloading data.

The teacher recalled an example once told by Khun Yai: while riding past a market in Bang Rak, she saw a vendor with goods laid out, waiting for customers. She said that if it were her, she would simply command in her mind for the goods to sell out — and they would. This is the same principle: bind your mind to the outcome you want, repeat the intention, and a powerful being will help bring it about. Most people have no power of mind because they've bound their minds to things without power, wasting time and opportunity for nothing. It's far better to bind the mind to a monk of pure practice, a genuine teacher, or the Triple Gem and Nirvana itself. The more you practice this, the easier it becomes.

Why does imagining something that hasn't happened yet still feel so genuinely joyful?

Someone shared an experience: while expanding their mind to be larger than the universe, they felt bold enough to make a great aspiration — recalling a celestial being who had once given enormous alms, they aspired to give in the same way, and made themselves feel, in the moment, as though they were truly the donor presiding over that offering. An overwhelming sense of joy welled up, with tears streaming down, even though it was only imagined and hadn't actually happened. Why could it feel so genuinely joyful?

The teacher explained that this comes from mindfulness, faith, and wisdom arising together, gathered within the quality of concentration — sustained, focused attention — driven by effort aimed at success. When you can genuinely feel that success in the present moment, you can draw the joy of a future success into the present, much like drawing on future income to use right now. What matters is doing it with sincerity, not just playacting, because sincerity is itself a quality of the wholesome system — and when sincerity is present, the wholesome system takes over as guide and sets the blueprint for success in motion.

A generous mind draws in more merit than you'd expect

Someone shared another example: normally, when offering several sets of items to monks, they would feel joy proportional to the quantity given. But once, offering only four sets, they made themselves feel that everyone in the dining hall shared in the merit together with them — and it felt as though they had gained merit from all the food in the entire hall. Why does that happen?

The teacher explained that this is because the mind is itself the substance of accomplishment: a spacious mind can hold far more goodness than a narrow one. The more generously you extend your mind, the more it expands — and that expansiveness is itself refinement. The more the mind expands, the more detail becomes visible, and the more deeply you come to understand other people's hearts; the inner guide, in turn, is able to point out finer and finer detail. This is why it's worth training the mind to be spacious and refined as a matter of habit.
