Life isn't complicated. The reason it appears complicated to you is because you are in a very distorted state of mind. That's the basic premise of Buddhism - that you're in a very distorted state of mind.

When you die in this life, you might be experiencing pain, but the structure of your perceptual field will determine your next lifetime. That structure has been determined by the way you have led this life.

In the western philosophy you can't perceive infinities at every moment. It's not there to do.

The state of mind that you are in causes you to act in a certain way. Your actions will bear results. The ultimate result of all karmas and actions is state of mind. You are your state of mind.

If you learn to lead your life strategically and strongly, you can overcome the opposition. But running away, you never overcome anything. The pathway to enlightenment is for the warrior, the samurai.

In this lifetime you can lose everything. Everything passes here. But you don't lose any spiritual knowledge that you have gained in this or any other lifetime. It is inside you.

The emphasis in tantra is not what you find yourself doing, it's on meditation.
