ਸਾਚੇ ਤੇ ਪਵਨਾ ਭਇਆ ਪਵਨੈ ਤੇ ਜਲੁ ਹੋਇ

"ਸਾਚੇ ਤੇ ਪਵਨਾ ਭਇਆ ਪਵਨੈ ਤੇ ਜਲੁ ਹੋਇ ॥ ਜਲ ਤੇ ਤ੍ਰਿਭਵਣੁ ਸਾਜਿਆ ਘਟਿ ਘਟਿ ਜੋਤਿ ਸਮੋਇ ॥"
"Saache te pavna bhea pavne te jal hoe. Jal te tribhavan saajiaa ghatt ghatt joy samo."
Translation: "From the True Lord came the air, and from the air came water. From water, He created the three worlds, infusing His Divine Light into every heart."

सोहं गंगा ॐ जमुना

सोहं गंगा ॐ जमुना, घट ही में संगम होय । 

सुरत शब्द जहाँ मलै, बहुर न मन्थन कोय ॥ 

सोहं कुंजी और ॐकार के जाप से उस घट का पट खुलता है

काया नगर का ताला भारी, सोहं कुंजी पावे । 

ॐकार का जाप जपे जब, घट का पट खुल जावे ॥

Guru AmarDas Ji gave boon to Bibi Bhani Ji

Yes, this is a well-known and profound episode in Sikh history. The event highlights the deep devotion of Bibi Bhani Ji and marks a pivotal turning point in how the succession of the Sikh Gurus took place.

According to traditional Sikh chronicles (Sakhi), the event unfolded as follows:

The Incident of the Broken Stool

One morning, while the third Sikh Guru, Guru Amar Das Ji, was deeply absorbed in meditation, Bibi Bhani Ji (his daughter) noticed that one of the legs of his low wooden bathing seat (chauki) was cracking and about to collapse. Fearing that the sudden fall would disturb her father's divine meditation, she immediately placed her own hand and arm underneath the broken seat to support it.

A sharp splinter from the wood pierced her arm, causing her to bleed heavily. Despite the severe pain and the flowing blood, she remained completely still and held the heavy platform until Guru Amar Das Ji finished his devotions.

The Boon and the Prophecy

When Guru Amar Das Ji opened his eyes, he was deeply moved to see his daughter bleeding just to protect his peace. Impressed by her unmatched spirit of Seva (selfless service), he told her to ask for any boon or favor.

Bibi Bhani Ji requested that the Guruship (Gur Gaddi) should remain within her lineage (the family of her husband, Bhai Jetha, who later became Guru Ram Das Ji).

Guru Amar Das Ji granted her wish but also gave a serious prophecy:

He foretold that by locking the succession within one family, she had "dammed the clear flowing stream" of the Guruship (which had previously been passed solely on non-familial merit).
He warned her that as a consequence, great sacrifices, torture, and heavy bloodshed would take place in her upcoming lineage.

Bibi Bhani Ji humbly accepted this, stating that sacrificing their lives for the truth would be an honor for her womb.

How the Prophecy Met Historically

True to the boon, the Guruship remained within her family from that point forward. However, just as Guru Amar Das Ji prophesied, her direct descendants faced immense martyrdom and shed their blood to protect righteousness:

Her youngest son, Guru Arjan Dev Ji, became the first Sikh Guru to be brutally martyred by the Mughal Empire.
Her great-grandson, Guru Tegh Bahadur Ji, was publicly executed in Delhi.
Her great-great-grandson, Guru Gobind Singh Ji, sacrificed his entire family—including all four of his sons (the Chaar Sahibzade)—in the fight against tyranny.

Guru Nanak Lineage

If you mean Guru Nanak Dev Ji’s lineage in the sense of the Dasam Granth/Ram-vansh tradition, I can explain the traditional genealogy connecting Sri Ram → Lava/Kusha → Sodhi/Bedi lineages → Guru Nanak and Guru Gobind Singh.

If you mean Guru Nanak’s historical family lineage, then Guru Nanak Dev Ji was born to Mehta Kalu (Kalyan Chand Bedi) and Mata Tripta of Talwandi (Nankana Sahib), and belonged to the Bedi Khatri lineage.

Guru nanak lineage

If you mean Guru Nanak Dev Ji’s lineage in the sense of the Dasam Granth/Ram-vansh tradition, I can explain the traditional genealogy connecting Sri Ram → Lava/Kusha → Sodhi/Bedi lineages → Guru Nanak and Guru Gobind Singh.

If you mean Guru Nanak’s historical family lineage, then Guru Nanak Dev Ji was born to Mehta Kalu (Kalyan Chand Bedi) and Mata Tripta of Talwandi (Nankana Sahib), and belonged to the Bedi Khatri lineage.

Which one do you want: the Dasam Granth/Lav-Kush genealogy, or Guru Nanak’s historical family genealogy?

Show whole tree

Yes. If you mean the genealogical tree described in Bachittar Natak of the Dasam Granth, the broad tree is as follows. The text connects the Sikh Gurus’ Bedi/Sodhi lineages to the traditional Suryavanshi/Raghuvanshi lineage of Raja Ram, through Lava and Kusha.

The important point

According to this Dasam Granth narrative:

• Raja Ram → Luv and Kush

• The descendants associated with Luv become the Sodhi line.

• The descendants associated with Kush become the Bedi line after becoming learned in the Vedas.

• Guru Nanak Dev Ji is presented as belonging to the Bedi line.

• Guru Angad Dev Ji belonged to the Trehan clan.

• Guru Amar Das Ji belonged to the Bhalla clan.

• Guru Ram Das Ji belonged to the Sodhi clan.

• From Guru Ram Das Ji onward, the succeeding Gurus through Guru Gobind Singh Ji are described as his Sodhi descendants. 

There is also a particularly interesting part in Bachittar Natak: the Bedi chief gives a blessing to the Sodhi king, saying that in the Kali age he would be known as Nanak, and the Sodhi would eventually receive the Guruship. The narrative then describes the Guruship passing Nanak → Angad → Amar Das → Ram Das, followed by the Sodhi Gurus. 

One important qualification: this is the genealogical account presented in the Dasam Granth tradition, not a modern historically verified biological genealogy. The exact historical ancestry of these ancient figures is a separate question.

If you want, I can next show you the actual Bachittar Natak verses, line-by-line, from Ram → Luv/Kush → Bedi/Sodhi → Nanak → Ram Das → Gobind Singh, including the original Gurmukhi and Hindi explanation.
