Can a Guru do the job of raising kundalini for the upAsakA?I know many won't do it,but is it possible?
The moment the disciple receives Mantra Upadesham, his (or her) Kundali is awakened from the sleep it was in prior to the initiation.
This is in fact the very purpose of Mantra Diksha to awaken the Kundali and to purify it.
Shri ChadikovAcha ----
mantra-dhArana-mAtrena tatkshanAt tanmayo bhavet |
jivAtmA kundali-madhye pradipakalika yathA ||
Shri ChandikA said---- The moment the disciple receives the Mantra, the Kundalini (the Jiva within the Kundalini) is awakened like a lamp's wick.
Shri MAtrikA Bheda Tantra; Patala 14; Verse 1.
As long as the Upashaka's Kundali is still in slumber there is no scope of any kind of spiritual upliftment or perfection (neither Siddhi nor Sadgati).
And, since Mantra Diksha serves the purpose of arousing the Kundalini Shakti from sleep, it is considered as the first step towards any kind of spiritual progress which ultimately ends with final liberation.
So, the short answer is, the SathGuru awakens the disciple's Kundalini at the moment of initiation itself.
It is also possible for a SathGuru to completely awaken the Kundalini Shakti of the disciple at the moment of Diksha and can even move it up till the highest Chakra i.e. the Sahsrara Chakra.
This is possible through Shaktipat (or the transfer of energy that happens due to the Guru's grace).
On the topic of Shaktipat there is an answer already.
In it you will see about three kind of initiations being talked about --- Sparsha, Drik and Manas.
SparshakhyA Devi DriksangyA MAnasAkhyA Maheswari |
KriyAyAsAdirahitA Devi DeekshA TridhA SmritA ||
O Devi, O Maheswari, Sparsha, Drik and Manas --- Dikshas are of these three kinds. In these three Dikshas elaborate rituals (Ayasha and Kriya) are not needed.
Kularnava Tantram, Chpater 14, Verse 34.
Among these three, during the Manasa Diksha, the Guru helps pierce the disciple's Shat Chakras and move his Kundalini upwards.
This is also known as Manasa Deeksha or Mano Deeksha or the Vedamayi Deeksha. (Manas is mind). Here the Guru meditates on the Kulakundalini Shakti which is situated within the four petaled lotus in the disciple's Muladhara Chakra. And meditating thus, he moves the Shakti upwards by piercing the Shatchakras and unites it with Shiva, who is in the Sahsrara Chakra. By doing so, by the Guru's order, the disciple gets rid of the three Pashas namely Sahaja, Agantuka and Sangsagika. The disciple is then filled with Shivatva and becomes like no other than the supreme Shiva. This Deeksha is considered as the one to give the quickest results among all and also as the most fruitful among all Shaktipat Deekshas.
So, it is very much possible for SathGurus.
