There was never a time when I did not exist, nor you, nor any being. Nor is there any future in which we shall cease to be. That which is non-existent can never come into being. That which is can never cease to be. That reality which pervades the universe is indestructible. No-one has the power to change the changeless. Bhagavad Gita
The smile is a very important feature of the human face. But because of human intelligence ,even that good part of human nature can be used in the wrong way, such as sarcastic smiles or diplomatic smiles, which only serve to create suspicion. I feel that a genuine affectionate smile largely depends on ones own attitude.It is illogical to expect smiles from others if one does not smile oneself.
Therefore, one can see that many things depend on ones own behaviour.
Our experiences and feelings are mainly related to our bodies and minds. We know from our daily experiences that mental happiness is beneficial.For instance, through two people may face the same kind of tragedy, one person may face it more easily than the other due to his or her mental attitude. Dalai lama
"Truth resides in the heart of every man. And it is there that he must seek it, in order to be guided by it so that, at the least, it will appear to him. But we do not have the right to force others to see the truth in our way."Mahatma Gandhi
" Attachment follows the experience of pleasure-Aversion follows the experience of pain-Clinging to life is the sentiment which causes its own potency to flow equally even in the wise-Their operations are to be got rid of by meditation" Bengali Baba; Yogasutra Patanjali
