Yonimudrā part II

In Kubjikāmatatantra I found a long passage dedicated to mudrā-s. It starts with Devi-s request for Bhairava to explain three mudrā-s and particularly yonimudrā.

śrīkubjikā uvāca

triśikhā padmamudrā ca yonimudrā viśeṣataḥ /
tāsāṃ lakṣaṇam ākhyāhi yathāvat sphuṭato vada // KubjT_6.49 //

śrīkubjikā said:

[For] trident, lotus and yoni mudrā particularly
please explain [me] their characteristics ! Properly [and] openly tell me!
Then Bhairava explain her several variants of these mudrā-s. Here is the first variant of yonimudrā that is to be used in meditation adoration and the procedure of driving deities away at the end of these (visarjana).

Here is its description:

padmamudrā samākhyātā yonimudrām ataḥ śṛṇu
hastābhyāṃ sampuṭaṃ kāryaṃ madhya yojayet //6.55 //

padmamudrā being told, now you listen yonimudrā!
With both hands a cup is to be done, the little and middle [fingers] joined,

puṭākārau karau kṛtvā aṅguṣṭhau madhyasaṃsthitau
niḥsṛtā vāmahastasya aṅgulyā tu kanīyasī // 6.56 //

after making the hands to form two pockets the thumbs are placed in the middle
[and] with left hand thumb prominent, oh Kanīyasī!

yonimudrā smṛtā bhadre sarveṣāṃ kṣobhakārikā
etā mudrāḥ samākhyātā dhyānapūjāvisarjane // 6.57 //

Yonimudrā which makes all tremble [is now] explained, o gracious!
These mudrā-s are declared for the meditation, adoration and evacuation [of deities].

The mudrā part of kubjikā is really interesting so I'll allow it more time for study.
