We need others for our physical, emotional, and spiritual well-being. Without others we are nothing. Our sense that we are an island, an independent, self-sufficient individual, bears no relation to reality. It is closer to the truth to picture ourself as a cell in the vast body of life, distinct yet intimately bound up with all living beings. We cannot exist without others, and they in turn are affected by everything we do. The idea that it is possible to secure our own welfare while neglecting the welfare of others, or even at the expense of others, is completely unrealistic.
Geshe Kelsang GyatsoAll objects whether pleasant, unpleasant or neutral, are mere appearances to the mind just like things experienced in a dream
Geshe Kelsang GyatsoWe know that we are happy when our mind is peaceful, and unhappy when it is not. It is therefore clear that our happiness depends upon our having a peaceful mind and not on good external conditions. Even if our external conditions are poor, if we maintain a peaceful mind all the time we shall always be happy.
Geshe Kelsang GyatsoHappiness and suffering are states of mind, and so their main causes cannot be found outside the mind.
