Human potential is the same for all. Your feeling, "I am of no value", is wrong. Absolutely wrong. You are deceiving yourself. We all have the power of thought – so what are you lacking? If you have willpower, then you can change anything. It is usually said that you are your own master.
His Holiness the Dalai Lama
Mind, which is like lightning, a breeze, or passing clouds,
Is coloured by its various thoughts of everything under the sun,
But when examined thoroughly is found to lack a basis or origin.
Just like a mirage on the horizon, it is devoid of essential nature.
While being empty, it appears; and while appearing, it is empty.
Everything in this world, including yourself, your emotions, your feelings and senses, all are fully interdependent. Nothing is independent... And yet, we are not smart enough to understand or realize it.
Interdependence itself indicates to you that everything is not existing by itself, as it appears to be to you. So, this is Emptiness in the Buddhist philosophy. Emptiness, Voidness or Shunyata, is the thing that is not really existing as it appears to be because of it being interdependent.
Gyalwang Drukchen Rinpoche
