Swami Satyasangananda Saraswati has done amazing work and this work will keep her name in eternity. This book is the best commentary I have read on Soundarya Lahari among the few commentaries I read so far. This commentary by Swami has been written keeping in mind for a common man/ woman. It is written in simple way and easy to understand.
Swami was personally trained for Mother Goddess worship by Guru Swami Satyananda. He trained a group of sanyasins and Swami was the lead among them. Saundarya Lahari has traditionally 100 slokas, in some other places, it is considered to be 103 slokas. Each sloka is 4 line sanskrit verse. Swami considers each sloka as a mantra. Swami has done both verbal japa and writing japa of the mantras. She had also hand drawn each of the Yantra pictures, about a dozen time for teaching and training purposes. She has mastered tantra and yantra. This book reflects her personal and inner experiences.
This book's front cover some what resembles Swami's earlier book Sri Vijnana Bhairava Tantra The Ascent (SVBT), in red colour and showing Sri Chakra. Out of 510 pages, first 92 pages are written only for introduction, similar to SVBT. The big introduction covers glimpse of various mantras and gives the big picture, after connecting the mantras to each other. Next 320 pages are commentaries on each of the 103 mantras. Each of 103 mantras of SL has been given in sanskrit script, then in english with sanskrit pronounciation, then word by word meaning, over all meaning, relevance of the words used and then commentary. Swamiji has also given meditation exercises on some verses/ slokhas. I personally like the moon meditation and has been practicing for a while. Last 98 pages speak about prayoga and appendices for sanskrit text and english translation, glossary, index, etc.
First 41 mantras describe the mystical experience of the union of Shiva and Shakti and related phenomena. The opening mantra (sloka 1) provides complete theme of Soundarya Lahari, union of Shiva and Devi. Remaining and last mantras describe the beauty of the Goddess in the order of top to bottom (the descent). As per traditional practice one is not supposed to be discussing mantras openly. So I am not privileged. However I can say that commentaries on the mantras are excellent and providing deep and great insights. I felt the inner sensation of being in Her presence while reading the book. I would say thanks and appreciation to author who has written in simplified, eloborative way.
I would recommend this book for a serious Tantra Practitioner or aspiring Practitioner.
If some one seeks specific benefits, he/she/ they can pray to Goddess Devi by chanting these mantras, either with one mantra or multiple mantras or entire Soundarya Lahari itself, for a specific number of times during each day. For best benefits, one should practice the mediatation or chanting at 4 am with complete faith and surrender to Her and the he/she/they can see the results with in few days. Mantra Japa is very powerful. I vouch for it with my personal experience.
