Gen Rabten once said our Tantric training is like fractals. Fractals are patterns that repeat themselves at different levels. Fundamentally, Tantric practice is about learning to meditate on Lamrim at increasingly subtle levels of mind. The fractal pattern is always Lamrim, but it appears in different ways at increasingly subtle levels of mind.

Our starting point is the world of our grossest levels of mind, the world we normally see or perceive. Here, we train in Lamrim of our daily life, go to Dharma centers, attend teachings, etc.

The next level is the world of our guru yoga practice, from going for refuge up to dissolving the guru into our heart. Here we are no longer in the world we normally see, but not yet in the pure land. I like to think this takes place in the charnel grounds, which is like a way station en route for Keajra.

The next level is gross generation stage. According to New Essence of Vajrayana, we can view this as our gross deity body is the celestial mansion, Mount Meru, the four continents and elements, and so forth.

The next level is the body mandala. This is like a half-way point between gross generation stage and completion stage. Our completely purified channels and drops appear as the deities of the body mandala.

The next level is the mantras. The mantras are by nature our completely purified inner winds. Since all minds are mounted on inner winds, we can almost say the flow of mantras is like the body mandala meditation of our body mandala meditations. In other words, just as the body mandala is our channels and drops appearing as their completely purified nature in the aspect of the deities of the body mandala, the deities of the body mandala appear in their completely purified nature in the aspect of the mantras.

The next level is the seed letter of the guru deity at our heart, the principal object of our completion stage meditation. This is the completely purified nature of the mantras and thus everything that came before them. It is by nature our very subtle wind and mind, our continuously residing wind and mind.

The next level is inside that we find the clear light Dharmakaya of our Mahamudra meditations. Just as all rivers empty into the ocean, all Dharma minds empty into the ocean of the Dharmakaya.

Inside that we find the union of appearance and emptiness, or full enlightenment.

The more time we spend at each of these levels, the more they start to feel like actual places – actual lands or worlds within our mind – each inside the other like Kadampa Russian dolls with increasing levels of subtlety and purity. In the beginning, we spend most of our mental time at the grossest levels, but with training we move more and more into the subtler and subtler levels of mind.

I think we can say when we reach the world of gross generation stage we have attained outer Keajra. Keajra itself has many layers up to the inner pure land of the Dharmakaya and finally definitive Keajra or the mind of full enlightenment.

When I do my three year retreat, I plan on spending a certain number of months in each of these worlds. The first six months will be mostly in the gross deity body. The next six months will be mostly in the body mandala. The next six months will be mostly in the mantras. The next six months will be at the level of seed letter. The next six months after that will be at the level of the Dharmakaya of Vajrayana Mahamudra, and the next six months after that will emphasize the union of appearance and emptiness. All throughout, I will try to integrate the full Lamrim into each world, so while what appears will be the different appearances of that world, what is understood is the full Kadam Lamrim.

In this way, we can gain lived experience in these different worlds, at these increasingly subtle levels of purity. In effect, we are forging our path within our mind from the world we normally see to the enligthened worlds, with all the stops in between. By training in this way, when we die, the path is made and we follow it to the pure land and beyond. It may take several lifetimes of doing this, but eventually we will have built the entire path within our mind.

Heruka Tantra is sometimes called “the main gateway for those seeking liberation.” I think quite literally Guru Heruka is not just the final result, but the entire path from where we start to the final destination. When we train in this way, we not only build our own pathway to enlightenment, we create an infrastructure that other beings can likewise travel on to the same destination. If we check, this is what Venerable Geshe-la has done for us, now we can do it for others.

How wonderful!
