The term nirviśēṣa or ‘featureless’ denotes an absolute experience but can be comprehended conceptually only in a relative sense

In a comment on one of my recent articles, The ego is essentially a formless and hence featureless phantom, a friend called ‘Sleepwalker’ quoted a sentence from its thirteenth section, Can self-awareness be considered to be a feature of the ego? (which I had quoted from We are aware of ourself even though we are featureless, the second section in one of my earlier articles, Being attentively self-aware does not entail any subject-object relationship), namely “When we say, ‘I slept peacefully last night’, we are expressing our experience of having been in a state in which we experienced no features”, and asked whether the peacefulness of sleep is not just a feature.

Since the concept of nirviśēṣatva (featurelessness or absence of any distinguishing features) is a significant and useful idea in advaita philosophy, and since it is very relevant to the practice of self-investigation, I decided to write the following detailed answer to this question:

Prāṇāyāma is just an aid to restrain the mind but will not bring about its annihilation

In a comment on one of my earlier articles, The fundamental law of experience or consciousness discovered by Sri Ramana, a friend called Chimborazo wrote:

Michael, sometimes it is said that the source of the ego (all thoughts, ‘I’-thought) is the heart. And the same heart is said to be the source of the breath. Therefore thoughts and breath have the same source. So if one holds one’s breath no thoughts would rise.

I cannot confirm that and I did not learn it in my experience of meditation. Please could you comment on this or clarify.

In reply to this I wrote a comment in which I explained:

Attending to our ego is attending to its source, ourself

A friend recently wrote to me referring to one of my recent articles, The ego is essentially a formless and hence featureless phantom, and asked:

In your most recent post there appears to be two subtly different forms of Self-Inquiry. On the one hand, there is a section in which we are told to turn the attention directly at the ego-I, investigating it. Doing so, it will disappear and be known to be a phantom. On the other hand, in another section, we are told to investigate the source, or “place” from which the ego-I rises in order to annihilate it.
