They are all good but I'd recommend these two series of starters:

Here is a meditation technique I find helpful.

A Transmutation Practice: Ham-Sah
There are diverse esoteric systems for transmuting the seminal
entity into sexual energy. Certainly, the most powerful one (the
Arcanum A.Z.F.) has to be performed by a man and a woman - we are
talking specifically about the Sahaja Maithuna, sexual yoga, White Tantra;
elsewhere we will give all the details for that practice. Now, for the
moment we are going to explain an exercise that can be practiced by
single people as well as by those who are married. I am going to tell
you the technique just now; please pay attention...
Sit down comfortably: the eastern way (cross-legged) or the western
way (on a comfortable armchair). Relax your bodies as children do.
Inhale deeply, very slowly, and imagine that the creative energy
rises through the spermatic channels up to the brain; mentally
pronounce the mantra HAM like this: HAAAAAAAMM.
Exhale, short and quick, as you pronounce aloud the mantra SAH: SAAAAHH...
Undoubtedly, you inhale through the nose and exhale through the
mouth. While inhaling, you “mantralize” the sacred syllabe HAM
(mentally, since you are inhaling through the nose); but you can
articulate the syllabe SAH with sound while you exhale.
The marvelous symbol that in the East makes the chaotic waters of life fertile is Ham-Sah, the Third Logos.
Usually, the sexual forces flow outwards from the inside in a
centrifugal way and that is why there are nocturnal emissions; when you
have a dream based on the Sexual Center, there occurs an emission, a
loss of sacred sperm or spermatic liquor...
If one organizes one’s vital systems and instead of propitiating the
centrifugal system, uses the centripetal system, that is, if one makes
the sexual forces flow inwards from the outside through transmutation,
then there are no emissions even if there may be erotic dreams.
One needs to organize one’s sexual forces if one wants to avoid
emissions; such forces are closely linked with one’s nourishment, with
the prana,
with life - that is obvious. Therefore there is a profound relation
between one’s sexual forces and one’s breathing, so that when both are
duly combined and harmonized, they bring about fundamental changes in
one’s physical and psychological anatomy.
To make the sexual energies “re-flow” inwards and upwards in a
centripetal way is what matters; only thus is it possible to produce a
specific change in the office and functions that the sexual creative
force can fulfil. During meditation one needs to imagine the creative
energy in action, making the energy rise to the brain in a rhythmic,
natural way by means of vocalising the mantra HAM-SAH, not forgetting
to synchronize the inhalations and exhalations of air in perfect
concentration, harmony and rhythm.
Let us make it clear that inhalation has to be deeper than
exhalation simply because we need to make the creative energy flow
inwards from the outside; that is, we need to make exhalation shorter
than inhalation.
With this practice there comes a moment when all the energy flows
inwards and upwards. Clearly, the creative energy so organized - in a
centripetal way - becomes an extraordinary instrument for the Essence,
a means to awaken consciousness.
I am teaching you genuine White Tantra; this is the practice used by
the Tantric Schools in the Himalayas and the Hindustan; this is the
practice through which one can achieve Ecstasy or Samadhi, or whatever
you want to call it.
They have spoken much about the Illuminating Void
and clearly we can experience it ourselves. It is in that Void where we
can find the Laws of Nature as they are in themselves and not as they
seem to be. In this physical world we only see the mechanism of causes
and effects but we do not know the Laws of Nature in themselves,
whereas in the Illuminating Void we can recognise them in a simple,
natural way, just as they are.
We have been told that a suction pump is needed in order to form a
void; we have such a pump in the spinal column and the channels Ida and
Pingala through which the creative energy rises to the brain. We have
also been told that a dynamo is needed; we have that in our brains and
strength of will. Finally in any technique, obviously there must be a
generator; fortunately, our generator is the creative organs, sex, the
sexual force.
Having the system and all the elements, we can form the Illuminating
Void; the pump, the dynamo and the generator are the elements that we
need in order to achieve the Illuminating Void in meditation. Only
through the absolute Void can we get to know that which is real.
In fact, the Illuminating Void is produced because the creative
energies flowing inwards from the outside, impregnating the
consciousness and eventually making it leave the ego and the body.
Extracted from the ego as if out from a bottle, in the absence of ego
and outside the physical body, the consciousness undoubtedly goes into
the Illuminating Void and receives the Tao.
Therefore, the creative energy combined with meditation serves to
awaken the consciousness. Unquestionably, it draws the consciousness
out from the ego and into absorption in the Illuminating Void.
Meditation combined with Tantra is tremendous. HAM-SAH is the key...
