Old Path, White Clouds will tell you much you need to know, with simple and elegantly straightforward writing.. Good choice!
Meditation - simple.. sit in your most comfortable position (if you can do full lotus, all the better, but the goal is not dependent on the condition of sitting in any particular position, or sitting period), and don't do anything at all. Don't try to calm your mind, don't think fancy visualizations, just sit and observe your own mind - this is a good place to start, as your own mind is all you actually ever experience anyway
What you do from there is up to what you need in order to understand and how fast you can understand.. Some people need whole convoluted dogmatic religions with worship, ritual and steps to follow to build up to the goal, some can do so directly and need nothing more than observing their own mind, and everything in between.. No one can tell you what in particular you will need, you'll just have to see what you can see by reading texts, listening to teachings (lots on youtube for example), and so on.
Here's an ancient text that might confuse you, or might make you go Hmmmmmm!
The Song of Mahamudra by Tilopa
Mahamudra is beyond all words and symbols,
But for you, Naropa, earnest and loyal, must this be said.
The Void needs no reliance; Mahamudra rests on naught.
Without making an effort, but remaining natural,
One can break the yoke thus gaining liberation.
If one looks for naught when staring into space;
If with the mind one then observes the mind;
One destroys distinctions and reaches Buddhahood.
The clouds that wander through the sky have no roots, no home,
Nor do the distinctive thoughts floating through the mind.
Once the Self-mind is seen, Discrimination stops.
In space, shapes and colors form
But neither by black nor white is space tinged.
From the Self-mind all things emerge;
The Mind by virtues and by vices is not stained.
The darkness of ages cannot shroud the glowing sun;
The long eons of Samsara ne'er can hide the Mind's brilliant light.
Though words are spoken to explain the Void, the Void as such can
never be expressed. Though we say "the Mind is a bright light,
" it is beyond all words and symbols. Although the Mind is void
in essence, all things it embraces and contains.
Do naught with the body but relax;
Shut firm the mouth and silent remain;
Empty your mind and think of naught.
Like a hollow bamboo rest at ease your body.
Giving not nor taking, put your mind at rest.
Mahamudra is like a mind that clings to naught.
Thus practicing, in time you will reach Buddhahood.
The practice of Mantra and Perfections, instructions in the Sutras and
Precepts, and teaching from the Schools and Scriptures will not bring
realization of the Innate Truth. For if the mind when filled with some
desire should seek a goal, it only hides the Light.
One who keeps the Tantric Precepts yet discriminates, betrays the
vows of Awakening,
Cease all activity; abandon all desire; let thoughts rise and fall as they
will like the ocean waves.
One who never harms the Non-abiding nor the Principles of non-distinction,
upholds the Tantric Precepts.
He who abandons craving and clings not to this or that,
Perceives the real meaning given in the Scriptures.
In Mahamudra all one's sins are burned; in Mahamudra one is released from
the prison of this world. This is the Dharma's supreme torch. Those who
disbelieve it are fools who ever wallow in misery and sorrow.
To strive for liberation one should rely on a Guru. When your mind receives
the Guru's blessing emancipation is at hand.
Alas, all things in this world are meaningless; they are but sorrow's seeds.
Small teachings lead to acts. One should only follow teachings that are great.
To transcend duality is the Kingly View; to conquer distractions is the
Royal Practice; the Path of No-practice is the Way of the Buddhas. 0ne who
treads that Path reaches Buddhahood.
Transient is this world; like phantoms and dreams,
Substance it has none. Grasp not the world nor your kin;
Cut the strings of lust and hatred; meditate in woods and mountains.
If without effort you remain loosely in the "natural state,"
soon Mahamudra you will win and attain the Non-attainment.
Cut the root of the tree and the leaves will wither;
cut the root of your mind and Samsara falls.
The light of any lamp dispels in a moment the darkness of long eons;
The strong light of the mind in but a flash will burn the veil of ignorance.
Whoever clings to mind sees not the truth of what's beyond the mind.
Whoever strives to practice Dharma finds not the truth of Beyond-practice.
One should cut cleanly through the root of the mind and stare naked.
One should thus break away from all distinctions and remain at ease.
One should not give and take but remain natural, for Mahamudra is beyond
all acceptance and rejection.
Since the consciousness is not born, no one can obstruct it or soil it;
Staying in the "Unborn" realm all appearances will dissolve into the
All self-will and pride will vanish into naught.
The supreme Understanding transcends all this and that.
The supreme Action embraces great resourcefulness without attachment.
The supreme Accomplishment is to realize immanence without hope.
At first a yogi feels his mind is tumbling like a waterfall;
In mid-course, like the Ganges, it flows on slow and gentle;
In the end, it is a great vast ocean,
Where the lights of Child and Mother merge in one.
