Yes, you are correct. But it was revealed by Lord Hayagrīva in a conversation between Him and Sage Agastya, as mentioned in the Brahmāṇḍa Purāṇa.

It is for Goddess Sarasvati. Not for Tārā or Mātaṅgī.

Good day to you as well! Your information seems to be right. There are two different variations of the Kāli yantra with the inner triangle pointing downward or upward. The deities you point out also seem to be correct, but I would suggest verifying in Mantra Mahodadhi (Ram Kumar Rai for the English Translation) for complete information.

Sir I have done 50 recitation of this kavach for times but I am with no results or any I can identify specifically, Also can I use this kavacham to siddh veer or vetal or the pach maha Vidya snice they are followers of Shri maha Kali. Please help

Nice information..But Lalitha Sahasranamam was composed by eight Vaak Devis right?

Is 'aim' the main bija?

Namaskar Raviji, Can you please suggest an appropriate stotra of Devi RajMatangi for developing musical abilities and attractive voice. E.g. Shamala Navarathna Malika.

Good evening Guruji Mother Kali is my favorite devata and I love the Goddess dearly. I want to worship her through her yantra. However, that task has been for me quite difficult since I have not been able to find a Kali Yantra Puja Vidhi that I can use as reference point. Nonetheless, I have read a lot and I have done a lot of research in order to learn as much as I can. Yet I still need help actually I need your help. This is what I know thus far with respect to the following Mother Kali yantra: https://i.pinimg.com/originals/2c/11/78/2c1178317e0c534971b7674d86535979.jpg I know the mantra associated with that yantra is: Krīm̐ Krīm̐ Krīm̐ Hūm̐ Hūm̐ Hrīm̐ Hrīm̐ Dakṣiṇe Kālike Krīm̐ Krīm̐ Krīm̐ Hūm̐ Hūm̐ Hrīm̐ Hrīm̐ Svāhā. I do not know who the petha devatas are. Could you help me Guruji Coming from the outside in: The Dwara Devatas are probably: Vaṭuka, Yoginī, Kṣetrapāla and Gaṇapati. Are there more Guruji? I assume that The Guardians of the 10 directions and their weapons are the same with any other yantra I know for sure the Bhurpura devatas are: East: Bhairavi, South-East: Mahabhairavi, South: Simhabhairavi, Sout-West: Dhumrabhairavi, West: Bhimabhairavi, North-West: Unmattabhairavi, North: Vashikaranabhairavi, North-East: Mohanabhairavi. For the flower petals, they are divided into two parts: top and bottom The top parts are probably inhabited by the Matrikas: Brahmani, Maheshvari, Kumari, Vaishnavi, Varahi, Indrani, Chamundi, and Chandi. The bottom parts are probably where the Bhairavas are found: Asithanga Bhairava, Ruru Bhairava, Chanda Bhairava, Krodha Bhairava, Unmatha Bhairava, Kapaala Bhairava, Bheeshana Bhairava, and Samhaara Bhairava. The dots that intersect between the flower petals I have actually no clue which devatas are there. The five triangles that’s where one can find the Kali Nityas: Kali, Kapalini, Kula, Kurukulla, Virodhini, Vipracitta, Ugra, Ugraprabha, Dipa, Nila, Ghana, Balaka, Matra, Mudra, and Mita. Bindu: Dakshine Kali.

The pedestal deities are generally different between two deities. The ynatra pūjas will also differ.

Today is both Lord Hayagrīva and the Divine Mother Gāyatrī devi jayanti. Thank you for providing the information on Lord Hayagrīva for the benefit of everyone on this auspicious day! We will definitely strive to provide more mantras and related stotras of Lord Hayagrīva and other Vaiṣṇava deities in future. Hopefully by next year, we may have an article to commemorate the jayanti day of both Lord Hayagrīva and Goddess Gāyatrī devi.
