Scientists may study mainly matter but they cannot ignore the human mind, or consciousness: spiritual practitioners may be engaging mainly in developing the mind but they cannot completely ignore their physical needs. It is for this reason that I have always stressed the importance of combining both mental and the material approach to achieving happiness for humankind.
Dalai LamaThe more you think about your own self, the more self-centred you are, the more trouble even small problems can create in your mind. The stronger your sense of 'I', the narrower the scope of your thinking becomes; then even small obstacles become unbearable. On the other hand, if you concern yourself mainly with others, the broader your thinking becomes, and life's inevitable difficulties disturb you less.
Dalai LamaWith a basic understanding of all humans as brothers and sisters, we can appreciate the usefulness of different systems and ideologies that can accommodate different individuals and groups with different cultural heritages, having different dispositions and tastes. Each person has the right to choose whatever is most suitable, on the basis of a deep understanding of all others as brothers and sisters.
