All Vedic Meditation teachers have been trained over years to a gold standard. What's more interesting is that each teacher is independent. This means that there's no exact dogma, belief system, or theology for everyone – every teacher is different and individual, just like you.
The only promise a teacher makes is to offer Vedic Meditation with the consistency, precision, and professionalism found in Vedic Meditation teachers worldwide.
Teachers are trained to a high standard with 2 years of dedicated study, followed by 3-4 month of intensive 14hr-a-day deep meditation practice in seclusion. This means your teacher has spent the time to understand meditation on a fundamental level. Your teacher made a promise to teach full-time and give daily meditation practice it's full respect. For your teacher, this isn't a passing fad.
Over the years, the fundamental practice of Vedic Meditation has had many names, but initially, it was the Grahasta technique – a technique designed specifically for people in ancient India to practice, so they could experience everything the monks/yogis in the mountains were ... without having to sit on a cold floor for six years to find it.
It was (and still is), a technique designed for life.
