When a Guru curses a person, can that curse be removed by God?
For Example, Lord Parashurama placed a curse on Karna, but Karna was not able to recover from the curse. Are there any situations where the curse of a Guru was overthrown by Gods?
Guruh pitA gururmAtA gururdevo maheswarah |
Shive rushte gurustrAtA gurau rushte na kaschana ||
Guru is the father, Guru is the mother, Guru is Lord Maheswara. When Shiva is angry the Guru can be the savior, but when Guru himself is angry none can save.
KulArnava Tantram 12.49
Similar verses from the "GurugitA Stotram" found in the ViswasAra Tantram:
Munibhih pannagairvapi surairvA shApito yadi |
KAlamrityubhayAdvApi guruh rakshati pArvati ||
Ashakta hi surAh sarve ashaktA munayastathA |
GurushApahatAh kshinAh kshayam yAnti na samshayah ||
O PArvati, if the disciple gets cursed by the Munis or by the NAgas or by the Gods, the Guru protects him. The Guru can protect the disciple from even KAla (Yama or death) and from the fear from death. But if Guru himself curses the disciple, then the disciple gradually becomes feeble and eventually attains destruction. And the Gods or the Munis are unable to save him [from the curse] in such cases.
Verses 63,64 of GurugitA Stotram found in ViswasAra Tantram.
So, generally it is believed that no one can save the disciple from a Guru's curse. Of course the Guru here is a SathGuru who meets the standards of the scriptures.
....A partial answer.
Yagyanyavalkya got cursed from his Guru and forgot all Vedas he learnt. As a result he worshipped Maa Saraswati.
Buddhi stotra by Yagnyavalkya starts:
krupam kuru jagan matar mamevam hat tejasam ||
guru shaapaat smruti bhrashtam vidya hinam cha dukhitam ||
The above stotra belongs to the Brahmavaivarta Purana.
In Hinduism, Guru comes before anyone else, even before God. Also, the first Guru of any human is his/her mother, then comes his/her father then comes the one who teaches other things.
A guru can save you from wrath of any God or rishi or anyone other by showing you the way. But if anyone makes his Guru angry then no one can save him.
It is not that a Guru's curse has more power than anyone. It is just that when you get cursed by anyone the Guru can show you the right path as to minimise the curses's effect, but when you get cursed by Guru then no one can show you any path as you angered the one who shows you the path.
