In the Shri Siddha Kunjika stotram, there is a following verse:
na sūktaṃ nāpi vā dhyānaṃ na nyāso na vārcanaṃ |2|
In the Shri Siddha Kunjika stotram, there is a following verse:
na sūktaṃ nāpi vā dhyānaṃ na nyāso na vārcanaṃ |2|
From the image you have attached:
Na kavacham na argala stotram kilakam na rahasyakam |
Na suktam na api va dhyanam na nyaso na va archanam ||
I have broken up few words here (वार्चनम् = वा + अर्चनम्) so that we can understand the meaning better.
Here Lord Shiva is saying that by reciting only this Stotra one gets the fruits of reciting Sri Chandi (Devi Mahatyam).
Kunjika patha matrena durga patha phalam labhet ||
Now, for reciting Sri Chandi there are certain rules. For example, first one should recite Argala Stotra, Kilaka Stotra, Devi Kavacha etc. One also has to do Nyasa, recite Rigvedokta Devi Sukta, Dhyana sloka and also has to do a archana (worship) before starting the actual recital.
But, in the case of reciting this Siddha Kunjika Stotra none of the above requirements are to be fulfilled.
Na kavacham na argala stotram kilakam na rahasyakam -- That means Argala/Kilaka and other Kavacha Stotras are not required to be recited here.
Na suktam na api va dhyanam na nyaso na va archanam --- That means reciting Devi Sukta, reciting Dhyanam or doing Nyasa are not required. Doing worship is also not required.
Navarchnam -- worship is neither (not even) required. This is the meaning you are looking for.
