The biography of the 15th Karmapa notes that he had a vision in which he simultaneously saw 25 reincarnations of Jamgön Kongtrul. The most famous of these was Karsey Kongtrul.
Jamgön Kongtrul's song of homage to honor the achievements of his heart disciple, the 15th Gyalwa Karmapa, who in return would become his root lama in the next life. The introduction and some verses (published in “The Rain of Wisdom”):
“Through resolving to rely on nothing other than the guru and through the powerful longing of a mind saddened by the ways of this dark age, I sang this song which is called ‘The Mirror that Shows What is to be Accepted and Rejected,’ in the melody of the cuckoo bird, the queen of spring:
Lord of incomparable kindness, lord guru,
Glorious Vajradhara, widely renowned,
The Karmapa of completely victorious buddha activity,
Is he not the glorious Khakyab Dorje?
With a mind of devotion, your son cries out.
Does the father jetsün hear me?
From the pinnacle of the height of existence down to the hell realms,
All beings are tormented by suffering;
Please look upon them with an eye of compassion.
In general, there is no happiness in the state of samsara.
In particular, the beings in an age when the five corruptions are rampant
Insatiably practice evil deeds.
Their minds are not in accord and one hates the other.
Even loving parents are murdered.
People are arrogant and think that they are not capable of hypocritical actions.
What preparations have they made to benefit their next life?
Even their present actions have no more than a sesame seed’s concern for the ultimate goal.
No matter how I look at this, I feel sad. (…)
Listen here, old Paldenpa!
If you act now, act virtuously.
If your mind plans, plan for the next life’s benefit.
The teachings of the sutras and tantras are vast and limitless.
Fully realizing the complete dharma
Is not for you of unworthy karma.
Although you may be trustworthy, how could someone like you
Carry the burden of the spiritual and temporal teachings?
(…) Contentment is the inexhaustible wealth, the essential jewel.
Fill your treasury with this jewel that cannot be lost; that will be good.
Do not let loose the enemy, the five poisons.
If the father guru ornaments the top of the head, that is beautiful. (…)
The refuge of beings of ill-fortune in the snow land of Tibet,
The Great Compassionate One, should be supplicated.
Sing the respected little song of six syllables.
Do not keep your body ordinary; meditate on it as a deity. (…)
The infallible jewels are the supreme refuge.
They are all embodied in the glorious guru.
Keep your trust in him, both now and in the future.
It is up to you, guru, whether this lowly one is happy or sad.
This servant has no one to depend on but you.
Father Karmapa, please look on me with kindness.
“Thus, the lazy one called Karma Palden Khyentse Öser, who is crowned with the name of the Dharmaraja Jamgön, wrote down spontaneously whatever arose in his mind.”
When the 2nd Jamgön Kongtrul left his seat at Tsadra Rinchen Drag to perform the parinirvana ceremonies for Traleg Rinpoche at Thrangu Monastery, he indicated to one of his secretaries, the late Changdö Buddha, that he would not return after the ceremonies. On the way, he visited the 9th Sangye Nyenpa Rinpoche at Benchen Monastery. There he told Sangye Nyenpa Rinpoche that he might die and would be very happy, if he would visit him if this happened.
Sangye Nyenpa Rinpoche arrived at the cave of Mipham Rinpoche in Thrangu Monastery shortly before Palden Khyentse Öser dissolved his mind into parinirvana. He called out the name of the 15th Karmapa, Palden Khyentse Öser's root lama, and the 2nd Jamgön Kongtrul Rinpoche smiled and passed away peacefully and joyfully. It was May 10, 1953 – he was 51 years old.
