On Theravada and Vajrayana

I was asked to translate this piece (posted a few days ago) into English. Here it is:

Someone asked me whether she could still go to a Theravada temple despite the fact that she is practicing Vajrayana Buddhism. The fact that the question was asked is because the questioner thinks Vajrayana and Theravada are different religions. In fact, the two are all important parts of Buddhism. If any Tibetan Buddhist practitioner thinks that she cannot prostrate to Buddha in a Thai temple any longer, she actually doesn't understand her own practice nor Buddhism. In my opinion, any Buddhist can prostrate or pay respect even to the images of teachers in other religions because they all show the ways to happiness. The prostration, however, is not to take these teachers as refuge. So the answer is that when we think we are Vajrayana Buddhist we are already Theravada and Mahayana at the same time. Our motivation in practicing may be a bit different, but the core of the teaching is the same—Four Noble Truths, Discipline, Meditation and Wisdom, Law of Karma, impermanence, compassion—they are all the same.
