Actually I've enquired with some friends and found out that this thangka was actually commissioned by one of Geshe Kelsang Gyatso's student. If we have a higher resolution image we can see that one of the Guru's depicted in the thangka is actually Geshe Kelsang Gyatso!
Anyhow it is a very very beautiful peace of thangka!
However i did some research and I found something interesting that I did not know... the very text that Lama Tsongkhapa is holding on the lotus on his left is actually the text of Prajnaparamita sutra!
So if Dorje Shugden arose from under Lama Tsongkhapa's throne and is the protector of Lama Tsongkhapa's teachings then isn't obvious he would also be protecting Prajnaparamita teachings too! Amazing... the more and more we discover... the more and more we are finding out how Dorje Shugden is truly the King of all Protectors form our time.
Attached her a cut out page from the book that talked about the text that Lama Tsongkhapa is holding
Mother of the Buddhas: Meditation on the Prajnaparamita Sutra
Thank you dsiluvu... this fact I too did not know. It is amazing how irrevocably linked Dorje Shugden is to Buddha's teaching!
The Prajnaparamita Sutra contains the highest teachings of the Buddha and is among the most holy of texts.
The Pajnaparamita mantra famously concludes the shorter version of the Heart Sutra:
Body is nothing more than emptiness,
emptiness is nothing more than body.
The body is exactly empty,
and emptiness is exactly body.
The other four aspects of human existence --
feeling, thought, will, and consciousness --
are likewise nothing more than emptiness,
and emptiness nothing more than they.
All things are empty:
Nothing is born, nothing dies,
nothing is pure, nothing is stained,
nothing increases and nothing decreases.
So, in emptiness, there is no body,
no feeling, no thought,
no will, no consciousness.
There are no eyes, no ears,
no nose, no tongue,
no body, no mind.
There is no seeing, no hearing,
no smelling, no tasting,
no touching, no imagining.
There is nothing seen, nor heard,
nor smelled, nor tasted,
nor touched, nor imagined.
There is no ignorance,
and no end to ignorance.
There is no old age and death,
and no end to old age and death.
There is no suffering, no cause of suffering,
no end to suffering, no path to follow.
There is no attainment of wisdom,
and no wisdom to attain.
The Bodhisattvas rely on the Perfection of Wisdom,
and so with no delusions,
they feel no fear,
and have Nirvana here and now.
All the Buddhas,
past, present, and future,
rely on the Perfection of Wisdom,
and live in full enlightenment.
The Perfection of Wisdom is the greatest mantra.
It is the clearest mantra,
the highest mantra,
the mantra that removes all suffering.
This is truth that cannot be doubted.
Say it so:
Gaté, gaté, paragaté, parasamgaté. Bodhi! Svaha!Which means...
Gone, gone, gone over, gone fully over. Awakened! So be it!
