The Noble Eightfold Path (the path, hereafter) is the guideline of right practice.
Buddha created the path based on his own experiences of the right practice.
Buddha confidently stated that anyone who seriously respected the path of the right practice would be able to purify consciousness to be fully enlightened, to be able to eliminate sufferings, and to let consciousness become a purified part of the ultimate consciousness.
"Right View" means correct understanding of the four noble truths.
"Right Intention" means your recognition and acceptance of the Buddha's truths based on the middle way approach and applications of the principle of dependent origination in everyday life.
Without the right intention, your right practice will not be able to let you learn and understand the truths correctly.
As the result, you will not be able to attain the final salvation in everyday life.
"Right Effort" means serious efforts to keep right actions in daily life.
In order to make sure you keep making such efforts, the path suggests "Right Livelihood", which means spiritual life of a monk.
Needless to say, this does not mean that we should become monks in temples at all.
This really means that we should keep mindsets of monks in everyday life.
Once you begin the right practice, you should keep the mindset to seek for spiritual satisfaction.
Buddha explained the right effort in more detail by concepts of "Right Speech", "Right Action", "Right Mindfulness", and "Right Concentration.
" The right speech means to pay spiritual attention whenever you speak.
For example, you must pay attention to contents, ways of expressions, wording, situations, and timing of your verbal expressions.
Sometimes, you are upset about how differently other people take your expressions.
This is because you did not pay enough spiritual attention to your expressions or wording before you actually talked.
The right action means not only doing right actions, but also right thinking.
More precisely, the right action means you do not kill, steal, drink alcohol, get involved in unethical sexual actions, and fall for spiritual materialism.
In order to do these actions, you must have right ways of thinking as well.
The right mindfulness has two meanings.
The first meaning is spiritual tolerance to everything around you.
If you have the right mindfulness, you will be able to notice everything around you and accept them without prejudice, personal desires, or personal preferences.
Being mindful will not only bring selflessness but also purify consciousness.
The second meaning of the right mindfulness is ability to distinguish bad desires from good desires.
Finally, the right concentration means right meditation.
Meditation is one of effective tools to create chances to notice, accept, and experience the truths.
There are three types of meditation and the first type is the meditation for reflection.
This is to create chances for you to understand, digest, and accept the truths.
The meditation for selflessness is the second type.
This meditation creates chances to let your consciousness experience nirvana.
There are four levels of this meditation.
In level one, you will be able to feel peace while your focus is not strong yet.
In level two, you will feel profound happiness since you can focus very well.
In level three, you will experience pure peace with less sense of time since your focus is now at high level and your consciousness is very close to the ultimate consciousness.
In level four, your consciousness will experience nirvana.
The meditation for the three subjects is the last type.
This meditation is about the best possible balance between three subjects, which are physical body, mind, and consciousness.
You will be completely relaxed, comfortable, honest, calm, merciful, and spiritual during and after this meditation.
While many will practice the meditation for the three subjects every day to maintain their spirituality, people will also use this as the introductory meditation prior to the meditation for reflection or the meditation for selflessness to create the best possible conditions of the three subjects for these meditations.
