Set aside personality. Focus on being a spiritual individual. Hatha yoga helps release stress and tension. Use subsuperconscious, not reason, analysis and intellect for understanding in an intuitive way. Let go of negative attachments, flow with the river of life in a natural way. Fulfill the highest dharma. Dissolve the seeds of desire.
