A bit I found on his website about Vajrayogini very inspiring !
Sacred secret practice
March 23, 2011
The following is a compilation of messages composed by His Eminence Tsem Tulku Rinpoche on the chat box at Rinpoche’s blog.

Did you know that the King of Dharma, Lord Tsongkhapa kept Vajra Yogini as one of his most precious and secret practices??? Lord Tsongkhapa practiced teachings from all the existing lineages of His time. He had 45 gurus from all lineages..
For Him to choose Vajra Yogini as one of His sacred secret practices, it means, Her path is still untainted, valid and very beneficial for those beings of this age. If Vajra Yogini is good enough for the King Of Dharma Tsongkhapa, it’s good enough for all of us for sure..Nothing further to check, because Lord Tsongkhapa has checked it for us already…
It’s like if His Holiness Dalai Lama or Kyabje Trijang Rinpoche says this practice is good, then it is good…full stop…
When we master the 11 Yogas of the sacred Vajra Yogini tantra, we master all phenomena that exist in all existence…All to be known in all planes/dimensions are directly and simultaneously perceived…homage to this Lady of Trauma who has elucidated the path to direct enlightenment.
This is my sacred shrine in my Ladrang to the Glorious Lady who is the supreme emanation of all Buddha’s perfections. She manifested at Mount Kailash Her complete and perfect Tantra.

Many great Mahasiddhas of India, Nepal, Mongolia, Tibet, China and now the world have accomplished what would have taken three aeons to accomplish within 14 short lifetimes…Buddhahood. May we be blessed to be able to master and accomplish Her practice.

I also placed a consecrated stone carved Vajra Yogini in my fish pond. All the fishes circumambulate around Her. Stone would be the most durable substance to enshrine Vajra Yogini’s essence/reminder since it’s outdoors although She is everywhere especially within ourselves. Finding the Vajra Yogini within ourselves makes all the problems, conceptions, unhappiness completely dissipate once and for all…
I love watching all the fishes swim around her and plant seeds of Buddhahood in their mindstreams. It is nice and peaceful at night. I have koi, oscars, parrot fishes, sucker fishes, river fishes all in this pond. Some of the fishes are over 12 inches in length and swim past Vajra Yogini so elegantly.
I have clay pots laid down nearby as shelters/homes for them. Parrot fishes loves these homes…they go in and out always. Super cute. I love animals so much and feel so good when they are ok….
I constantly bow to Vajra Yogini’s holy feet and wish all get connected with this profound practice. She is the Buddha who through Her practice can absorb all our samsaric traumas..hence she is the ‘Trauma Lady’…
Some will work so hard almost giving their lives for it to own a house, car, and go on trips. They spend so much energy, time and burn themselves out for these goals. But for higher goals such as Vajra Yogini’s practice, they find it too hard, ask how long more to go, feel like giving up, always have ups and downs non-stop, and question their progress that they put so little time into….for higher goals or the ultimate goals, the efforts will be beyond what you can ever imagine…but one day at a time and you get there.
Tsem Rinpoche
Abandoning Dharma is, in the final analysis, disparaging the Hinayana because of the Mahayana; favoring the Hinayana on account of the Mahayana; playing off sutra against tantra; playing off the four classes of the tantras against each other; favoring one of the Tibetan schools—the Sakya, Gelug, Kagyu, or Nyingma—and disparaging the rest; and so on. In other words, we abandon Dharma any time we favor our own tenets and disparage the rest.
