Since you mentioned Buddha specifically, I will post the Four Solaces, from the Kalama Sutta (an excellent sutta all around to check out) which is somewhat analagous to Pascal's Wager, which then leaves no pretzel logic excuse to not purify ones mind from the poisons of greed, hatred, and delusion in this life:
Kalama Sutta verse 17:
The Four Solaces
17. "The disciple of the Noble Ones, Kalamas, who has such a hate-free mind, such a malice-free mind, such an undefiled mind, and such a purified mind, is one by whom four solaces are found here and now.
"'Suppose there is a hereafter and there is a fruit, result, of deeds done well or ill. Then it is possible that at the dissolution of the body after death, I shall arise in the heavenly world, which is possessed of the state of bliss.' This is the first solace found by him.
"'Suppose there is no hereafter and there is no fruit, no result, of deeds done well or ill. Yet in this world, here and now, free from hatred, free from malice, safe and sound, and happy, I keep myself.' This is the second solace found by him.
"'Suppose evil (results) befall an evil-doer. I, however, think of doing evil to no one. Then, how can ill (results) affect me who do no evil deed?' This is the third solace found by him.
"'Suppose evil (results) do not befall an evil-doer. Then I see myself purified in any case.' This is the fourth solace found by him.
"The disciple of the Noble Ones, Kalamas, who has such a hate-free mind, such a malice-free mind, such an undefiled mind, and such a purified mind, is one by whom, here and now, these four solaces are found."
"So it is, Blessed One. So it is, Sublime one. The disciple of the Noble Ones, venerable sir, who has such a hate-free mind, such a malice-free mind, such an undefiled mind, and such a purified mind, is one by whom, here and now, four solaces are found.

"Marvelous, venerable sir! Marvelous, venerable sir! As if, venerable sir, a person were to turn face upward what is upside down, or to uncover the concealed, or to point the way to one who is lost or to carry a lamp in the darkness, thinking, 'Those who have eyes will see visible objects,' so has the Dhamma been set forth in many ways by the Blessed One. We, venerable sir, go to the Blessed One for refuge, to the Dhamma for refuge, and to the Community of Bhikkhus for refuge. Venerable sir, may the Blessed One regard us as lay followers who have gone for refuge for life, from today."
