For now you could do the Heart Sutra practice which does not need "empowerment, oral transmission and teachings" since it is a Sutra practice.
The Heart Essence of the Transcendental Wisdom
MA SAM JÖ ME SHERAB PAROL CHIN
Beyond word, Beyond thought, Beyond description, Prajnaparamita,
MA KYÉ MI GAK NAMKHÉ NGOWO NYI
Unborn, unceasing, the very essence of space,

Which can only be experienced as a wisdom of our own Rigpa

Homage to the Mother of the Buddhas of past, present and future!

In Tibetan: Victorious Mother Conqueror, the Essence of Transcendental Wisdom. In one bampo (A bundle).
DI KED DAG GI THOE PA DUE CHIG NA
Thus I have heard; Once upon a time
CHOM DEN DE GYAL POY KHAB JA KOED PHUNG POY RI LA

The Great Conqueror was dwelling in Rajagriha, the royal domain at Vulture Peak Mountain, together with the great assembly of Bikkshus

And the great assembly of Bodhisattvas
DEY TSE CHOM DEN DE ZAB MO NANG WA ZHE JA WAY CHOE KYI

At that time the Great Conqueror was absorbed in the samadhi of the many aspects of phenomena called ‘Profound Illumination’

SHE RAB KYI PHA ROL TU CHIN PA ZAB MOY CHOED PA NYID LA NAM PAR TA ZHING

And at the same time the Great Bodhisattva the Bodhisattva-Mahasattva Noble Avalokiteshvara,
Was absorbed in the profound practice of the Transcendental Wisdom.
He also saw the five aggregates to be entirely empty in nature.
DE NE SANG GYE KYI THUE
And then through the power of the Buddha
TSE DANG DEN PA SHARYI BUE JANG CHUB SEM PA SEM PA CHENPO PHAGPA CHENREZIG WANGCHUG LA DI KED CHE MRE SO
Venerable Shariputra said to Noble Avolokiteshvara, the Bodhisattva-Mahasattva in these words

“How should someone of noble family proceed in order to engage into the profound prajnaparamita – practice?”
DE KED CHE MRE PA DANG
Addressed in this way,
JANG CHUB SEM PA SEM PA CHEN PO PHAGPA CHENREZIG WANGCHUG GI
TSE DANG DEN PA SHA RA DO TYI BU LA DI KED CHE MRE SO
Noble Avolokiteshvara, the Bodhisattva-Mahasattva, said to Venerable Shariputra:

“Oh Shariputra, a son or daughter of noble family wishing to engage into the profound practice of the Transcendental Wisdom, should absolutely look at this way
PHUNG PO NGA PO DE DAG KYANG RANG ZHIN GYI TONG PAR NAM PAR
YANG DAG PAR JE SU TAWO
Like this: they should see that all of the five aggregates are completely empty and pure by nature.
ZUG TONG PA WO TONG PA NYID ZUG SO
Form is empty Emptiness is form
ZUG LE TONG PA NYID ZHEN MA YIN
Form is none other than emptiness
TONG PA NYID LE KYANG ZUG ZHEN MA YIN NO
Emptiness is also none other than form
DE ZHIN DU TSOR WA DANG DU SHE DANG
Likewise feelings, perceptions,
DU JED DANG NAM PAR SHEPA NAM TONG PAWO
Mental formations and all kinds of consciousness are all emptiness,
SHARYI BU DE TAR CHOE THAM CHED TONG PA NYID DE
O Shariputra! Likewise all phenomena are emptiness:
TSEN NYID MED PA MA KYE PA MA GAG PA DRI MA MED PA
There are no characteristics; No birth, No extinctions, No impurity
DRI MA DANG DREL WA DRI WA MED PA GANG WA MED PAWO
Free from stains, Neither decrease Nor increase!
SHARYI BU DE TA WE NA TONG PA NYID LA ZUG MED
O Shariputra! Therefore, in emptiness there is no form,
TSOR WA MED DU SHE MED DU JE NAM MED NAM PAR SHE PA MED
No feelings, No perception, No mental formation, No consciousness,

No eye, No ear No nose No tongue No body, No mind,
ZUG MED DRA MED DRI MED RO MED REG JA MED CHOE MED DO
No form, No sound, No smell, No taste, No touch, No phenomenon.
MIG GI KHAM MED PA NE YID KYI KHAM MED
From the sight up to the mind, there is no inherit quality in them
YID KYI NAM PAR SHE PAY KHAM KYI BAR DU ANG MED DO
And up to the mental consciousness, all do not have inherent quality
MA RIG PA MED MA RIG PA ZED PA MED PA NE GA SHI MED
There is no ignorance, Nor end of ignorance up to no old age and death;
GA SHI ZED PAY BAR DU YANG MED DO DE ZHIN DU DUG NGAL WA DANG
And also no exhaustion of old age and death. Likewise, there is no suffering,
KUN JUNG WA DANG GOG PA DANG LAM MED
No origin of suffering No cessation of suffering No path.
YESHE MED THOB PA MED MA THOB PA YANG MED DO
No wisdom, No attainment, and also no non-attainment!
SHARYI BU DE TA WE NA JANG CHUB SEM PA NAM THOB PA MED PAY CHIR
Shariputra! Therefore, since Bodhisattvas have no attainment
SHE RAB KYI PHA ROL TU CHIN PA LA TEN CHING NE TE
SEM LA DRIB PA MED PE TRAG PA MED DE
They rely on and abide in the profound practice of the Transcendental Wisdom.
Since there is no obscuration of mind, there is no fear,
CHIN CHI LOG LE SHIN TU DE NE NYANG NGEN LE DE PAR THAR CHIN TO
They transcend completely wrong views and definitely attain complete nirvana.
DUE SUM DU NAM PAR ZHUG PAY SANGYE THAM CHED KYANG
SHERAB KYI PHA ROL TU CHIN PA LA TEN NE LA NA MED PA YANG DAG PAR

Also all the Buddhas who dwell in all the three times
By relying upon the Transcendental Wisdom have attained unsurpassable,
Pure, perfect enlightenment and actualized perfect and complete Buddhahood.
DE TA WE NA SHERAB KYI PHA ROL TU CHIN PAY NGAG
Therefore the mantra of the Transcendental Wisdom,
RIG PA CHEN POY NGAG LA NA MED PA NGAG
The mantra of great insight, The unsurpassable mantra,
MI NYAM PA DANG NYAM PAR JED PAY NGAG
The mantra which equalizes one to the Unequalled One,
DUG NGAL THAM CHED RAB TU ZHI WAR JED PAY NGAG
The mantra which completely pacifies all sufferings,
MI DZUEN PE NA DEN PAR SHE PAR JA TE
Which is not false, should therefore be known as true.
SHERAB KYI PHA ROL TU CHIN PAY NGAG MRE PA
The mantra of the Transcendental Wisdom proclaims:
TAYA THA GATE GATE PARA GATE PARA SAMGATE BODHI SWAHHA
Gone, gone, gone beyond, completely exposed, awake, so be it.
SHARYI BU JANGCHUB SEM PA SEM PA CHEN POE

Thus, Shariputra this is how a Bodhisattva Mahasattva should train in the profound Transcendental Wisdom
DE NE CHOM DEN DE TING NGE DZIN DE LE ZUENG TE JANGCHUB SEM PA

Then the Victorious Conqueror arose from that samadhi and praised the Noble Avalokiteshvara,
The Great Bodhisattva, Bodhisattva-Mahasattva,
LEG SO LEG SO RIG KYI BU DE DE ZHIN NO
“Well said, Well said, son of noble family, it is so!
DE DE ZHEN TE JI TAR KHYOED KYI TEN PA ZHIN DU
SHERAB KYI PHA POL TU CHIN PA ZAB MO LA CHED PAR
Since it is so, the profound Transcendental Wisdom should be practised just as you have taught
JA TE DE ZHIN SHEG PA NAM KYANG JE SU YI RANG NGO
And likewise all the Tathagatas will rejoice.”
CHOM DEN DE KYI DE KED CHE KA TSAL NE TSE DANG
When the Victorious Conqueror proclaimed in this way,

And Noble Avolokiteshvara, the Bodhisattva-Mahasattva
THAM CHED DANG DEN PAY KHOR DE DAG DANG
And the whole gathering along with all retinues,

Gods, Humans Demi-gods, and all the worldly spirits of smell-eaters,
CHOM DEN DE KYI SUNG PA LA NGOEN PAR TOED DO
Rejoiced and highly praised the words of the Victorious Conqueror,
TAYA THA GATE GATE PARA GATE PARA SAMGATE BODHI SWAHHA (108+ repitions)
Gone, gone, gone beyond, completely exposed, awake, so be it.

I prostrate to the Sublime Mother, the Transcendental Wisdom.

May the truth of my words be accomplished.

As when the lord of gods, Indra Satakratu, by contemplating the profound meaning of the Transcendental Wisdom

And chanting the words, repelled all the negative forces and
All other inopportune circumstances, may I accordingly through contemplating
The profound meaning of the Transcendental Wisdom, the Sublime Mother, and by chanting the words,
DUED DIG CHEN LA SOG PAY MI THUEN PAY CHOG THAM CHED CHIR

Ward of all the unwholesome forces and all other unfavourable conditions.
(* Clap hands)
*MED PAR GYUR CHIG *ZHI WAR GYUR CHIG *RAB TU ZHI WAR GYUR CHIG
May they be annihilated! May they be pacified! May they be utterly pacified!
(At the end recite the following)
GANG GI TEN CHING DREL WAR JUNG
You who taught that whatever phenomena arise in interdependence,
GAG PA MED PA KYE MED PA
Are without stoppage and without generating,
CHE PA MED PA TAG MED PA
Are neither eternal, nor impermanent,
WONG WA MED PA DRO MED PA
Are neither coming nor going,

Are free from being one or multiple,

Having dissipated all these concepts,
DZOG PAY SANGYE MRA NAM KYI
You are the Perfect Buddha,
DAM PA HE LA CHAG TSEL LO
The most sublime one among humans! To you I prostrate!
Excellent advice, endorsed 100%.
My own guru would advise the same, and of course so do I.
