user760: A very short summary of the Vipassanā technique taught by S.N. Goenka would be: "observe your bodily sensations with equanimity". The role of physical bodily sensations is the key aspect of the technique and other traditions do not attach such a great importance to them. It is said that Goenka's technique of scanning the body to feel increasingly subtle sensations was passed on though several lay teachers and that it goes back to the Burmese monk Ledi Sayadaw.
Ledi Sayadaw left a large quantity of writings; some of them are available here and/or here. I looked through some of them, and in no place did I see any passage that would present observing bodily sensations as the technique to be followed. If he really taught this, it is hard to imagine he would not mention that this is the key aspect of the technique. Can anyone provide a relevant quote from Ledi Sayadaw's texts?
Update: The question is whether Ledi-style Vipassanā should be practised by observing bodily sensations/body scanning. Mindfulness of the body in Ānāpāna Dīpanī is presented as something distinct from Vipassanā, so it doesn't answer my question. Moreover, it looks like Ledi Sayadaw understood "mindfulness of the body" to mean "mindfulness of the breath", not body scanning. See Ānāpāna Dīpanī, part XIV:

[...] establishing mindfulness of the body (kāyānupassana satipaṭṭhāna). The out-breath and in-breath, being part of the aggregate of materiality (rūpakkhandha) are called body (kāya).


user15213: I think you could find Goenka’s instruction in the Anapana Dipani from Ledi Sayadaw. The Anapana Dipani is based on the Anapana Sutta, which is divided into four tetrads. The first three deal with Anapana meditation and the development of the jhanas, and the last one with vipassana meditation. Since Goenka it is not much interested in the development of jhanas, but in we all getting the nearest possible to the final goal, he’s instruction only refer to the frist and the last tetrad. This is perfectly accepted way to practice, in Ledi Sayada’s words:
“When Can One Proceed to Vipassanā? As the Ānāpānasati Sutta and its Commentary explain the order of practice in mindfulness of breathing, one is to take up work in the fourth tetrad only after one has attained the four jhānas. If one can adhere strictly to this order of practice, that is ideal, but if one cannot follow this sequence one may proceed to vipassanā, or insight, from the third jhāna. It is also permissible to proceed to vipassanā from the second jhāna, or from the first, or from the access stage prior to full attainment of jhāna, or from the connection stage, or even from the counting stage after one has overcome the wandering tendencies of the mind.”
Now, there are two methods to practice Vipassana meditation:
“One may proceed to vipassanā while still keeping the attention on the out-breath and in-breath, or one may treat the mindfulness of breathing as preparatory work and then proceed to vipassanā by taking any portion of the five aggregates (pañcakkhandhā) one wishes as the object of attention.”
Now, why did Goenka choose corporeal phenomena? Well, I think there are a number of reasons, but an important one is because the object of attention in Vipassana meditation depends on the level of concentration one has attained. Since a teacher needs to make sure that all he’s students are getting things right, he (I think) assume that the majority of the new students achieve only the counting and connection stages of concentration through Anapana meditation. And
“In these two stages, the work consists solely of keeping the attention on the out-breaths and in-breaths and perceiving them with wisdom. Hence, if one wishes to proceed to vipassanā from these stages, the effort must be based on corporeal phenomena (rūpa-dhamma)”.
Take another look at the Anapana Dipani, and you will find the answers you are looking for. I think that the specific instructions of Goenka are presented as “a way” but not as “the way”. He structured a meditation technique following Ledi Sayadaw’s teachings, but he did it having in mind that he will be teaching lay and wisdomless people. I think he offered us a great gift, kind of a shortcut to Nibbana (nothing short about it), and I’m very grateful for that.
Hope this helps you.

The Manual of Insight Vipassanā Dīpanī
By Ledi Sayadaw Mahathera
Translated by U Nana Mahathera:

The Practice of Insight Meditation
I will now indicate the main points necessary to those who practise the exercises of insight. Of
the three knowledges of insight, the knowledge of impermanence must first and foremost be
acquired. How? If we carefully watch the cinematograph show, we will see how quick are the
changes of the numerous series of photographs representing the wonderful scene, all in a
moment of time. We will also see that a hundred or more photographs are required to represent
the scene of a moving body. These are, in fact, the functions of viparinama and annathabhava, or
the representation of impermanence or death, or cessation of movements. If we carefully
examine the movements in a scene, such as the walking, standing, sitting, sleeping, bending,
stretching, and so forth, of the parts of the body during a moment of time, we will see that these
are full of changes, or full of impermanence. Even in a moment of walking, in a single step, there
are numerous changes of pictures which may be called impermanence or death. It is also the
same with the rest of the movements. Now, we must apply this to ourselves. The impermanence
and the death of mental and material phenomena are to be found to the full in our bodies, our
heads, and in every part of the body. If we are able to discern clearly those functions of
impermanence and death which are always operating in our bodies, we shall acquire the insight
of the destruction ( bhanga-nana ), into the breaking-up, falling-off, cessation, and changes of the
various parts of the body in each second, in each fraction of a second. That is, we shall discern
the changes of every part of the body, small and great, of head, of legs, of hands, and so forth. If
this be thus discerned, then it may be said that the exercise on the contemplation of
impermanence is well accomplished. And if the exercise on the contemplation of impermanence
is well accomplished, then that of the contemplation of non-soul is also accomplished. If this is
thus discerned, then it may be said that the exercise on the contemplation of impermanence is
well accomplished. By the word "accomplished," it is meant that the exercise has been properly
worked out so as to remain a permanent possession, during the whole term of life; but it is not
meant that the knowledge of the path and of fruition has been attained. The attainment of the
knowledge of the path and fruition, however, is quick or slow, according to opportunity or lack
of opportunity in the practice of higher virtues.
