The eightfold path combines the means leading to enlightenment. Firstly it’s important to develop wisdom, i.e. to overcome ignorance. Secondly one should act in a way to build up positive  Karma and to reduce negative Karma. Items 6, 7 and 8 describe the meaningful handling one’s own consciousness.
Developing wisdom
1. Understanding how suffering emerges, what are the causes of suffering und how to abandon suffering.
2. Thinking, to convert the recognized into action. Ignorance, hatred, attachment, jealousy, and pride (disturbing emotions) no longer determine our feeling and our actions.
Right action
3. Right speech: Not to lie, not to talk about others in a bad manner, not to talk nonsense.
4. Right limits of action: abandon actions that harm others.
5. Right livelihood: Leading a life that is determined by wisdom and compassion.
Working with mind
6. Right efforts: Raise energy and to meditate on the indestructible nature of mind.
7. Right mindfulness: Not to forget the object of concentration
8. Right profound absorption: holding mind in one place again an again and to develop the timeless qualities of mind by means of meditation.

[Skt. Nirmanakaya] For the benefit of other beings a  Buddha can manifest in many different forms. He does this due to his compassion. The most perfect of these forms is the so called emanation state of a Buddha. It has the 32 main characteristics and 80 minor characteristics of perfection. Is associated with the experience of non-conditioned compassion.

Disturbing Emotions

[Tib.Wang] A Ceremony which introduces the practitioner to the powerfield of a certain Buddha aspect. It may be given as a blessing to establish a bond to the teacher and to purify obstacles on the way to enlightenment. Or it is given at the start of a practice. One also needs a Lung, a reading of the text, and a Thri, the instructions on how to use it. The effectiveness of these methods in developing one's awareness cannot be overestimated.

[Tib. Tongpanyi, Skt. Shunyata] The fact that nothing outer or inner exists through or in itself. Everything arises from conditions, the ultimate nature of which is the potential of space.

[Tib. Chang Chub Kyi Sem, Skt. Bodhicitta] Attitude of a Bodhisattva, basis of Mahayana. It is the enlightened expression of minds clearness. Is expirienced when mind realizes its reachness of possibilities. Manifests in many Buddha forms.

Has two aspects: the relative means perfecting ourselves through the six liberating actions for the benefit of all beings. The absolute is spontaneous and effortless activity without thought or hesitation. The experience of subject, object and action as a totality makes this intuitive state automatic.

Complete enlightenment is a state of realization in which the most subtle traces of ignorance about the nature of reality are eliminated and highest wisdom - the state of omniscience - is attained; it is sometimes called "the embodiment of the Three Kayas".

Imagination of a meditation form, especially of a  Buddha aspect, as an expression of the enlightened qualities of mind.
