According to Osho, leaving a "secure" job simply exposes that its security was a dream; only awareness is real security. Take the risk: drop the egoic personality and fall awake into your individuality. In that awakening, fear of loss and death loosens, clarity and bliss arise, and you discover the only oasis - consciousness - a taste of deathlessness that cannot be taken away.
Letting go of a 'safe' job shows that true safety is waking up inside you, not in things outside.
