What does meditation mean for you ?

For an ongoing discussion with a philosophy teacher who did define meditation as super-consciousness, I looked up the most rudimentary definitions of the pragmatic Wikipedians:
a.) https://en.wikipedia.org/wiki/Meditation (points 1 – 6)
b.) https://en.wikipedia.org/wiki/Dhyana_in_Hinduism (points 7 – 11.3)
c.) https://en.wikipedia.org/wiki/Dhyāna_in_Buddhism (points 11.4 – 13)

1. “a practice where an individual uses a technique – such as mindfulness, or focusing the mind on a particular object, thought, or activity”
2. meditation is derived from Old French meditacioun, in turn from Latin meditatio from a verb meditari, meaning “to * think, contemplate, devise, ponder”
3. covers a wide range of dissimilar practices in different traditions
   *”think[ing] deeply about (something)”;
4. ” focusing one’s mind for a period of time”,
5. “the act of giving your attention to only one thing, either as a religious activity or as a way of becoming calm and relaxed”,
6. “to engage in mental exercise (such as concentrating on one’s breathing or repetition of a mantra) for the purpose of reaching a heightened level of spiritual awareness.”
   *to get beyond the reflexive, “discursive thinking”
7. Dhyana is taken up in Yoga exercises, and is a means to samadhi and self-knowledge.
8. “sustained attention”
9. and the “application of mind to the chosen point of concentration”
10. Dhyana is non-judgmental, non-presumptuous observation of that object.
11. Dhyana means contemplation and meditation.
    1. The root of the word is Dhi refers to “imaginative vision” and associated with goddess Saraswati with powers of knowledge, wisdom and poetic eloquence. It is a composite of three terms, namely dhyai,
    2. upasana (“dwelling upon”),
    3. and bhavana (“cultivating”).
    4. the term jhāna (Skt. dhyāna) is derived from the verb jhayati, “to think or meditate,” while the verb jhapeti, “to burn up,” explicates its function, namely burning up opposing states, burning up or destroying “the mental defilements preventing […] the development of serenity and insight.”
12. the training of the mind, commonly translated as meditation, to withdraw the mind from the automatic responses to sense-impressions, and leading to a “state of perfect equanimity and awareness
13. “to see, to look,” “to show.”

I did not find a terminology of super conscious there, so my understanding of meditation is that it is a tool to reach super consciousness, not the super consciousness in itself.
The difference being similar to define music as “excitement”, when in fact it can be a tool to reach excitement.
And the reason why I am so pedantic, is because I am of the opinion that especially in the non-material world we have to be very clear as to what we talk about in order to create a clear structure of the abstract realm of spirituality.
The earlier we get sloppy, the more muddled a picture becomes.

Now I ask you readers:
What does the word meditation mean to you specifically ?
