Mūlādhārambujā-rūḍhāa मूलाधारम्बुजा-रूढा (514)

Yogini who presides over this chakra is Sākinī, who is described in the next seven nāma-s till nāma 520.  This cakra is situated at the perineum area and has four lotus petals that are red in colour.  Each petal is inscribed with four consonants with bindu-s.  The pericarp of this cakra is square in shape with eight spears protruding outwardly.  Inside this pericarp, the bīja of this cakra laṁ (लं) is placed.  There is a red inverted triangle within the pericarp that flashes like lightning.  Inside this triangle, the powerful klīṁ bīja (क्लीं), also known as kāma bīja, is placed.  The bīja for earth is laṁ and this is appropriate because mūlādhāra cakra is the lowest cakra which is also known as the base cakra. Inside this triangle, there is a Liṅga (one of the prominent forms of Śiva).  Kuṇḍalinī energy in the form of a snake coiled around this Liṅga three and half times.  There is a hole which is called dvāra in Sanskrit in this cakra, through which Kuṇḍalinī ascends and descends.  Under normal circumstances, the mouth of this hole is blocked by the head of this snake.  This is the most important cakra as it holds the life energy in the form of Kuṇḍalinī here. Lalitāmbikā dwells in this cakra in the form of Kuṇḍalinī, Her subtlest form. Ancient scriptures refer the presiding deity of this cakra as Dākinī who is the presiding deity of viśuddhi cakra as per this Sahasranāma. 

The bīja laṁ is used for acquiring material prosperity.  The other bīja klīṁ which is placed inside the triangle also gives prosperity.  It is to be noted that kāmakalā (nāma 322), the subtler form of Lalitāmbikā is different from kāma bīja klīṁ referred here.

Pañca-vaktrā पञ्च-वक्त्रा (515)

Sākinī is five faced, hence described in this Sahasranāma as the fifth cakra.  Each of these faces represents five elements like ākāś, air, etc. 

There is a yantra called pañca-vaktrā, which is five faced, which was given by Śiva to Rāvaṇa, in appreciation of his penance. This is mentioned in the epic Rāmāyaṇa,. 

Asthi-saṁsthitā अस्थि-संस्थिता (516)

Sākinī presides over bones, the fifth layer from the skin. This is also one of the reasons for taking up this cakra as the fifth in this Sahasranāma. 

Aṅkuśādi-praharaṇā अङकुशादि-प्रहरणा (517)

Sākinī has weapons like elephant-hook.  She is said to have four arms and apart from elephant-hook, she also carries lotus, book and cin mudra (mudra of knowledge or jñāna mudra).  But scriptures disagree with these armories. Scriptures talk about śūla (trident), staff (a long stick with a flag tied at the top.  Generally it is carried by sanyāsi -s), gourd (kamaṇḍalu, a copper or brass vessel with a nostril like opening containing water) and rudrākṣa mālā. These are the symbols of a sanyāsi. 

Varadādi-niṣevitā वरदादि-निषेविता (518)

Sākinī is surrounded by her assistants like Varadā and three others.  The three others are Śrī (possibly indicating prosperity as Śrī means Lakṣmī), Śandā and Sarasvatī (goddess of knowledge).

Mudgaudanāsakta-cittā मुद्गौदनासक्त-चित्ता (519)

Sākinī is fond of food of made of green gram. The combination of mudgaudannā is rice mixed with green gram, jaggary, coconut, jīraka, ghee and milk.  For offering this to goddess, there is a specific method by which this is to be prepared. 

Sākinyambā-svarupiṇī साकिन्यम्बा-स्वरुपिणी (520)

The presiding deity of the mūlādhāra cakra is in the form of Sākinī who has been described in these seven nāma-s.
