[Advaita-l] Nitya Karma question

[श्रीमल्ललितालालितः]

All what is said above gives impression that there is no need to do
nitya-karma if one doesn't need brahma-GYAnam.
Or, to be more clear it gives us clear message that let us not do
nitya-karma, there is no harm in it.
Is that true ?

Whatever it may be, sha~Nkara-s words are not smR^iti. He is just saying
that abhAva can not produce anything. This is yukti. And it is clashing with
smR^itis, such as -
अकुर्वन् विहितं कर्म निन्दितं च समाचरन् ।
प्रसञ्जञ्श्चेन्द्रियार्थेषु नरः पतनमृच्छति ॥
(akurvan vihitaM karma ninditaM cha samAcharan.
prasa~nja~nshchendriyArtheShu naraH patanamR^ichchhati..)
This clearly says that non-performance of prescribed karma-s 'AND'
performance of prohibited ones, both cause downfall.

So, what's the way to save validity of smR^iti-s and accept logic both at
same time ?

Here says sha~Nkara :
नित्यानां चाकरणमभावः । ततः प्रत्यवायानुपपत्तिः इति । अतः
पूर्वोपचितदुरितेभ्यः प्राप्यमाणायाः प्रत्यवायक्रियाया नित्याकरणं लक्षणम् ।
(nityAnAM chAkaraNamabhAvaH . tataH pratyavAyAnupapattiH iti. ataH
pUrvopachitaduritebhyaH prApyamANAyAH pratyavAyakriyAyA nityAkaraNaM
laxaNam.)

It says that non-performance of nitya-karma points pratyavAya.

What does it mean ? Does it pacify the conflict between smR^iti and logic in
anyway ? Does it support that nitya-karma-s must be done in any way ?
