Use breath and sound as a vehicle. We must reach unstruck sound and uncreated light. This is the purpose of meditation. By gross sound one can catch subtle sound. When you catch the divine unstruck sound, consciousness unfolds, you dissolve, merge, and ultimately you become nothing.
Love is unconditional.
Love is perfect. Attachment and attraction is not love. Do not think about the fruit of your actions, otherwise you will lose everything. Love is the first principle. When you feel love then you can not forget it.
