In this class, Pema Khandro goes through the passage on pure and impure perceptions and explains that our perceptions appear only from within our own mind. Our perceptions of the same situation may shift from considering it pure versus impure.
She then explains how we can freely have sense perceptions, without any grasping and she narrates Longchenpa’s definition of freedom (from sense experiences). The definition of freedom refers to emptiness, and that emptiness is the answer to freely experience senses without grasping. Longchenpa teaches to see perceptions and sense experiences as magical empty appearances and not see them as true.
Pema Khandro then wraps up Mahayoga with raising the question that: what makes sense experiences binding? The answer is grasping and that we grasp because we have not realized empty appearances. Grasping causes us to be bound by our experiences.
In conclusion, she goes through different parts of Tantric path according to Mahayoga inlcuding view, meditation, commitments, enlightened activities etc. and explains each part in more details.
