Dear Sangha Members and Friends of the Padmasambhava Buddhist Center,

I have the great privilege to share with you one of the most beautiful announcements that I can make: the longtime wishes and prayers of all the PBC members and devoted disciples of Ven. Khenchen Palden Sherab Rinpoche have been answered.

Recently, His Eminence Terton Namkha Drimed Rinpoche discovered the reincarnation of Ven. Khenchen Palden Sherab Rinpoche on the eighth day of this month, just two days ago. He was given the name Palden Yonten Thaye Lodro Chokyi Gyaltsen!

At Padma Samye Ling, the North American Monastery of PBC, we enjoyed a great celebration for the 10th Day of Guru Rinpoche, and all the gathered Sangha rejoiced in this announcement with tremendous joy and excitement.

Now that we have discovered the reincarnation of Ven. Khenchen Palden Sherab Rinpoche, H.E. Terton Namkha Drimed Rinpoche is requesting that everyone recite many Dusum Sangye prayers of Guru Padmasambhava. This is my wish as well. We pray for the continued success of all the Dharma activities of Khenchen Yangsi Rinpoche, that there are no obstacles and everything unfolds very smoothly, for the fulfillment of all of his wishes, and that he will benefit the Teachings and all sentient beings for aeons.

Yours in the Dharma,
Khenpo Tsewang Dongyal

10th Day of Guru Rinpoche

vacuum properties of QCD

ActionAPE5LQanimXs30 ChargeAPE5LQanimXs30

The animations above illustrate the typical four-dimensional structure of gluon-field configurations averaged over in describing the vacuum properties of QCD [ Quantum Chromodynamics ]. The volume of the box is 2.4 by 2.4 by 3.6 fm, big enough to hold a couple of protons. Contrary to the concept of an empty vacuum, QCD induces chromo-electric and chromo-magnetic fields throughout space-time in its lowest energy state. After a few sweeps of smoothing the gluon field (50 sweeps of APE smearing), a lumpy structure reminiscent of a lava lamp is revealed. This is the QCD Lava Lamp. The action density (left) and the topological charge density (right) are displayed. The former is similar to an energy density while the latter is a measure of the winding of the gluon field lines in the QCD vacuum.

The animation at left was featured in Prof. Frank Wilczek’s 2004 Nobel Prize Lecture.

Now Broadcasting in Planck Definition : Craig J. Hogan

If reality has finite information content, space has finite fidelity. The quantum wave function that encodes spatial relationships maybe limited to information that can be transmitted in a “Planck broadcast”, with a bandwidth given by the inverse of the Planck time, about 2×1043 bits per second. Such a quantum system can resemble classical space-time on large scales, but locality emerges only gradually and imperfectly. Massive bodies are never perfectly at rest, but very slightly and slowly fluctuate in transverse position, with aspectrum of variation given by the Planck time. This distinctive new kind of noise associated with quantum geometry would not have been noticed up to now, but may be detectable in a new kind of experiment.

Pondicherry interpretation

An overview of the Pondicherry interpretation of quantum mechanics is presented.
This interpretation proceeds from the recognition that the fundamental theoretical
framework of physics is a probability algorithm, which serves to describe an
objective fuzziness (the literal meaning of Heisenberg?s term ?Unschärfe,? usually
mistranslated as ?uncertainty?) by assigning objective probabilities to the possible
outcomes of unperformed measurements. Although it rejects attempts to construe
quantum states as evolving ontological states, it arrives at an objective description
of the quantum world that owes nothing to observers or the goings-on in physics
laboratories. In fact, unless such attempts are rejected, quantum theory?s true
ontological implications cannot be seen. Among these are the radically relational
nature of space, the numerical identity of the corresponding relata, the incomplete
spatiotemporal differentiation of the physical world, and the consequent top-down
structure of reality, which defies attempts to model it from the bottom up, whether
on the basis of an intrinsically differentiated spacetime manifold or out of a multitude
of individual building blocks.

View of Atheras Bay. Putative location of the Cave of the Nymphs.

On the Cave of the Nymphs (Antr.), late third or early fourth century CE. It is one of the few
extant works of the Neoplatonic philosopher Porphyry and is a literary interpretation of eleven
lines from the Odyssey (13.102-12).

There is a leafy olive at its head,
And nearby a delightful misty cave,
Sacred to the nymphs who have the name of Naiads.
Inside are mixing-bowls and double-handled
Jars made of stone, and here the bees store honey.
Inside are long stone looms, at which the nymphs
Weave sea-blue webs, a wondrous sight, and streams
Of ever-flowing water. It has two doors,
One to the north, by which men may descend,
The other to the south, for gods. This way
Men enter not: it is the immortals path. 13.102-12

(…ἄντρον,) ὃ διὰ τῶν ἐπῶν τούτων διαγράφει λέγων·
αὐτὰρ ἐπὶ κρατὸς λιµένος τανύφυλλος ἐλαίη,
ἀγχόθι δ? αὐτῆς ἄντρον ἐπήρατον ἠεροειδές,
ἱρὸν νυµφάων αἳ νηιάδες καλέονται.
ἐν τῷ κρητῆρές τε καὶ ἀµφιφορῆες ἔασι
λάινοι· ἔνθα δ? ἔπειτα τιθαιβώσσουσι µέλισσαι.
ἐν δ? ἱστοὶ λίθεοι περιµήκεες, ἔνθα τε νύµφαι
φάρε? ὑφαίνουσιν ἁλιπόρφυρα, θαῦµα ἰδέσθαι·
ἐν δ? ὕδατ? ἀενάοντα. δύω δέ τέ οἱ θύραι εἰσίν,
αἱ µὲν πρὸς βορέαο καταβαταὶ ἀνθρώποισιν,
αἱ δ? αὖ πρὸς νότου εἰσὶ θεώτεραι· οὐδέ τι κείνῃ
ἄνδρες ἐσέρχονται, ἀλλ? ἀθανάτων ὁδός ἐστιν. Antr. 55.1.2-13.

(…the cave) ?At the head of the harbor is an olive tree with long-pointed leaves,
and near it a lovely and dark cave,
which is sacred to the nymphs called naiads.
Within are kraters and amphoras
of stone, where bees store up honey.
Tall stone looms stand inside as well, and there nymphs
weave sea-purple cloth?a wonder to see.
Within this cave water is ever-flowing. There are two gates,
one toward the north which leads downward for men,
and another toward the south which is divine.
Men do not enter by the latter way, rather it is a path for immortals.? Odyessy(13.102-12)


Titan Beyond the Rings










In 2006 April, Cassini captured Saturn’s A and F rings stretching in front of cloud-shrouded Titan. Near the rings and appearing just above Titan was Epimetheus, a moon which orbits just outside the F ring. The dark space in the A ring is called the Encke Gap, although several thin knotted ringlets and even the small moon Pan orbit there.
