A powerful method for a normal person: Gulu Renpoche's Yoga
In the Gulu Renpoche's yoga practice, you need to visualize yourself uniting with him. You Unite with the Gulu Renpoche as one, insight and out. You have his compassion, his wisdom, his speech, his action, his strength, his courage, his power, his youth and his purity.
Not only during the practice, or meditation period, but also through out the day, walking and sleeping as a real Bodhisattva.
