This verse is commenting on the development of Āsana
as a foundation or accessory for more subtle practices.
Better not to confuse the vehicle with the direction.
I am reminded of a quote from Srivatsa Ramaswami:
“I studied with Śrī Krishnamacharya for a number of years.
I do not remember a single Yogāsana class which did not have
a decent dose of Prāṇāyāma and Ṣanmukhi Mudrā in it
and short prayers to begin and end the session.”
parāñci khāni vyatṛṇat svayambhūs
tasmāt parāṅ paśyati nāntarātman |
kaś cid dhīrah pratyagātmānam aikṣad
āvṛttacakṣur amṛtattvam icchan ||
The self born creator bored the sense openings outwards,
so the self looks out at the world rather than inwards.
A wise person, wanting to taste the state of immortality,
stops the senses from moving outwards and turns within to the essence.
Kaṭha Upaniṣaṭ 2.1.1.
Non-perception (of Nature) is because of subtlety,
not because of non-existence,
since it (Nature) is perceived through its effects.
These effects are intelligence and the rest.
Some are similar to Nature and some dissimilar.
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā Eight
Comment from Gaudapādācarya Bhāṣya:
Even in the world, a son is similar as well as dissimilar to his father.
The causes of similarity and dissimilarity we shall explain later.
We may not perceive what is within the range of the senses (Pratyakṣa) because we are:
Blind or deaf to what is in front of us.
Not relating with what is there.
Seeing something between.
Letting something else dominate.
Confusing with something similar.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Śloka Seven
What about the supersensible?
“But, knowledge of what is beyond the range of the senses is from inference based on generalised correlation;
and knowledge not attainable even by that is attained though the eyes of another or authentic texts.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā Six
“Direct observation involves selective ascertainment through the senses.
Inference is of three kinds:
– The past shaping the future
– Projecting the whole from the part
– Forming a comparison from a similar.
Authentic authority is trusted words and teachings.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Śloka Five
“Primordial Nature is uncreated and yet creates.
Awareness is neither.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā Three
“The usual means to reduce suffering are linked to impurity, decay and excess.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā Two
“Within and around us is an absence of certainty and permanence.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Āryā One
