Perhaps Jesus strange words to Nicodemus in John 3, about being born again of water and the Holy Spirit may refer to the immortality yogas, such as kundalini yoga, which deal with conserving the sexual energy and lifting it upward, opening spiritual centres (chakras) until a new immortal self-being is born.
W-e-l-l ... we need to tread carefully here.
I am loathe to interpret Scripture through what is, effectively, an alien lens. There is virtue in comparison, but there is danger of misinterpretation if we let our understanding of 'that' doctrine influence our understanding of 'this' one.
So ... I would say neither He nor Nicodemus had any inkling of 'immortality yogas', 'kindalini' or 'chakras', and rather than look at the Scripture in those terms, I'd look to see what is, if indeed there is, an equivalent?
So I woud look at the Hebrew teachings on the soul, specifically:
nefesh (Hebrew) | psyche (Greek) | anima (Latin)
The animal or sanguinary soul ... every 'living' creature has this soul.
"for the life (nefesh) of every creature is the blood of it" (Leviticus 17:14)
"for the blood is the life (nefesh)" (Deuteronomy 122:23).
Ruach | nous/pneuma | spiritus
The mental soul
The term 'ruach' is used in many senses and can only be properly understood against in the total context of scripture. It means 'breath' (in the anthropological sense) or 'wind' (in the spiritual), and as such can express the principle of life, rather than an individual being:
"In whose hand [is] the soul (nefesh) of every living thing, and the breath (ruach)] of all mankind" (Job 12:10)
Ruach can imply a transcendant, transpersonal, quality, and as such we have not necessarily risen above the cosmological. Ruach in reference to the Spirit of God is Divine, but ruach in reference to the spirit of man is not. Further 'ruach' in the human sense can encompass error, "They also that erred in spirit [ruach]" (Isaias 29:44) and this can signify disorder, passion, even madness, "Terrors are turned upon me: they pursue my soul as the wind [ruach]" (Job 30:15), or "Behold, they are all vanity; their works are nothing: their molten images are wind [ruach] and confusion," (Isaias 41:29).
Neshamah (pneuma/pnoe | spiritus/spiraculum/habitus)
The spiritualised soul
Neshamah is the breath, be it human or divine. In Genesis God made man and 'breathed' into him, but the breath of God must necessarily convey more than simple animation. The Divine Breath not only animated humanity but conferred upon it a sanctified state, a state of grace (the descent of the Holy Spirit as 'tongues of flame' continues this idea), our Adamic or Primordial state.
Here great care must be taken to differentiate between neshamah as a natural quality of the human spirit, and neshamah as a supernatural quality infused by the Divine Breath, a situation made more difficult by ther apparent interchangeability of ruach and neshamah:
"All the while my breath [neshamah] is in me, and the spirit [ruach] of God is in my nostrils;"
Job 27:3
Whilst neshamah sanctifies man, it remains in and of itself Divine and forms no part of his individual nature: "The Spirit breatheth where he will and thou hearest his voice: but thou knowest not whence he cometh and whither he goeth. So is every one that is born of the Spirit." (John 3:8)
It is through neshamah we receive our life from God, it is in neshamah we participate in the Divine Life, and it is through neshamah we return to Him, "That which is born of the flesh is flesh: and that which is born of the Spirit is spirit," (John 3:6) upon the breath of prayer: "Let every thing that hath breath [neshamah] praise the Lord. Praise ye the Lord."
The distinction — which might be my perception rather than the doctrinal teaching — between the Abrahamic and the Asiatic doctrines is that of jiriki-tariki —
From wiki:
Jiriki (自力, one's own strength) is the Japanese Buddhist term for 'self power', the ability to achieve liberation or enlightenment (in other words, to reach nirvana) through one's own efforts.
Tariki (他力 other power, outside help) is what in Abrahamics would refer to the indwelling Spirit of God (Hebrew: shekinah, Christian Holy Ghost, Moslem baraka).
Jiriki is very much urged and practiced in Zen Buddhism. In Pure Land Buddhism, tariki often refers to the power of the Amida Buddha.
The two ways are not to be seen as mutually exclusive, or jiriki seen as "better" than tariki, although its appeal and perceived superiority to anti-religious sentiment in the west is undeniable.
The baseline for me is that whilst human nature is not in and of itself divine – it is a created nature after all – it is open to the Divine.
But only the Divine knows Itself — It's too exalted for a human nature to grasp:
"... but you have received the spirit of adoption of sons, whereby we cry: Abba (Father)."
(Romans 8:15) and "And because you are sons, God (the Father) hath sent the Spirit (God the Holy Ghost) of his Son (God the Son) into your hearts, crying: Abba, Father" (Galatians 4:6).
The point here is that it is the Holy Spirit who cries, He cries in us and we are caught up in that cry.
An aphorism of the Fathers is the Holy Spirit reveals the Son, the Son reveals the Father. Without the indwelling Shekinah/Holy Ghost/Baraka, when we see Jesus, all we see is the man.
Jiriki, self-power, is in undertaking the necessary discipline, to clean house, to invite the Holy Spirit into the soul, which then becomes a temple.

There is in the kabbala two further determinations of the soul - but these are degrees or modes of neshamah:
Hayah
The living soul
An awareness of the divine life force itself.
Yehidah
The one soul
In which one can achieve as full a union with God as is possible.
Both rabbinic and kabbalistic works posit that there are also additional non-permanent states (infused or inspired) of the soul that people can develop on certain occasions. These spiritual qualities play no part in any eschatalogical scheme, but are mentioned for completeness:
Ruach HaKodesh
The spirit of holiness
A state of the soul that makes prophecy possible.
Note: as healing is considered among the Divine Gifts of the Spirit, then I would posit, in accord with Rabbinic, Kabbalistic and Christian doctrine, that the 'realm' of healing is that of the ruach, which locates its function in the greater scheme of things.
Neshamah Yeseira
The supplemental soul that a Jew experiences on Shabbat. It makes possible an enhanced spiritual enjoyment of the day. This exists only when one is observing Shabbat; it can be lost and gained depending on one's observance.
Neshamah Kedosha
A spiritual quality related to the study and fulfillment of the Torah commandments. It exists only when one studies and follows Torah; it can be lost and gained depending on one's study and observance.
Note:
These two give a view of neshamah - whilst this spiritual quality is enhanced with regard to ruach, it is still within the human domain, but can aspire or attain to higher qualities when engaged corectly in 'higher' things. The former, 'Neshamah Yeseira' is liturgical (the proper observation of the sabbath) and again 'Neshamah Kedosha' is a state in contemplation of the Divine Mysteries - which again are most present and profound in the liturgy of the tradition in question.
Something to be going on with ...
