The only reason why we are still here is because we believe there is a reason to be here.
So why are we still swimming in the sea of samsara?
At this time, while you have all the opportunities, if you do not do your best to achieve the pure, stainless path to enlightenment when will you do it?
If you don't meditate, don't practise the graduated path to enlightenment, especially bodhicitta, in this life, then when?
When will you practise? When will you have this realization?
If, in this life, you don't achieve renunciation, bodhicitta and sunyata, as well as the two stages of tantra, when will you?
When will you have these attainments?
When will you become enlightened?
When will you perform perfect work for sentient beings?

-Lama Zopa Rinpoche
