"Tantra Ke Gopaniye Rahasya" - video by pujya Gurudev Dr. Narayan Dutt Shrimali

Before you do the Tara Mahavidya sadhana or any other sadhana in the coming days it is very important that you first know and understand all the rules to do a Tantric Ritual/ sadhana.
No sadhana or mantra chant can give you success if you do it without complete presence of your mind..... Many people say that while mantra chant although I try but my mind gets involves into other thoughts. I dunno how it is possible that you call yourself and how you will get success in sadhana in this way, even a 10 lakh mantra jap will be all useless if you do it in this way. Because, while sitting on sadhana you are not a household, you have nothing to do with the worldly affairs, if you want successs then for some time you will have to keep yourself mentally away from all these things.

Now, how will you do this ??

As I told earlier and in this video Gurudev has instructed that Mantra jap should be done continously in Krodh Mudra..... with red face, Fire... anger.... strength in the eyes, the whole bodies power should be concentrated in your eyes and you have to keep yourself strong and think that whatever mantra you are chanting it is happening and you are getting benefit of it. Your fingers, hands will be tight, whole body errect with anger.

If you cannot do that, then another option is that you perform TRATAK.
Tratak means looking at the tip of the oil lamp with a constant gaze. You do not have to close the eye lid or blink, even if tears come you will not blink and while doing this do the whole mantra jap. This activity also rises the Praan tattva in you and reach you to high level success, sure short guarantedd success... Also if you do not do it you will have to face sure short failure, because if you do not know how to concentrate and focus what you are doing then how do you think you will cause a change in Brahmand, because Tantra sadhana means you are creating a new scope in Brahmand.

2. Celibacy/Brahmacharya. It is the base of all sadhanas that you save your semen and also keep good thoughts in mind, because if you do not have that nothing can give you success, your body is not powerful enough then. Lord Hanuman is known as the most powerful Lord only because he has akhand Brahmacharya, not only this.. even during life time it should be kept in mind that try never to loose out semen, you should understand how just a few seconds temporary pleasure is obstructing your whole future scope and you life.

3.Eat pure satwik food and that too try to eat food from good people's house. Keep friendship with good people. Those buisinessmen and low quality people who speak lies all the day and cheat others, or who are not of good thoughts like you, please avoid their company,. They will ruin you in no time. Neither they will rise, nor will let you, so... Avoid liquor, beer-alcohol, cigaratte, speaking lies, non-vegetarian, telling lies during the sadhana period till the completion of the ritual.

Tantra sadhana is a very effective sadhana, not very complex also, but its very important that you do it in the correct way. If you fail to do it you will get nothing, then don't do it. And if you try once then there is nothing as good as this in this world, both both male or female.

Tantra Safalya Mantra- 5 mantra or its sound should come to you while the sadhana, it is useful in all kinds of Tantra sadhana.
