Devi Worship Dasa Mahavidya Names Introduction (ramanan50.wordpress.com)

Sir, Namaste. I always wanted to become a member of SriVidya family. So by this urge, I sought Shri. Bharadwaja Swamigal of Yogamaya Bhuvaneshvari Ashram and requested him to initiate me. He gave me the first four Mantras of SriVidya (1.MahaGanapathi, 2.Bala Thripurasundari,3.Bhuvaneshvari, 4.Navakshari) together and told me to do the japa everyday. In fact, I had expected only one mantra.
But being a beginner, doing four of them daily with all their respective nyasams took a long time and it became too much for my concentration. So I gave up the japam itself.
I want to do only one japam 108 times at a time. As I had given up, should I get initiated again? Should I seek another Guru? Would it become Guru apacharam? Or can I start simply with MahaGanapathi mantra? I’m a bit afraid to approach my Guru again. What should I do? Please reply. Thank You.
If you have been initiated already,do all Mantras. Difficulties in time management will be there initially and they will disappear and Mantra Siddhi will be easier.The difficulties you quoted are normal obstacles to test you. Regards

Very informative article about “Dasa Mahavidya Upasana”.
Here I would like to share my writings on Dasa Mahavidya.
I hope this information will helpful for all readers.
Thanks.
Thanks.Regards.
Thanks. Regards.
wonderful post with a major defect. The moment you are suggesting sacrificing an animal, this post has lost all it glory. Sacrifice yourself if you want but not an animal. Please don’t change the definition of sacrifice, sacrificing someone else is not called as sacrifice. No pooja, or prayer in Hindu culture encourage killing of an innocent animal. So, please rewrite your article for the betterment of humans.
It might be embarrassing to admit to killing of animals.Certain sects practiced it. I can not change facts .
Its good ur articles enlightning common people
Thanks,Regards
