Life is the journey from a limited consciousness to the vast and infinite, from darkness to light and more light. But when we reject life since it is limited we also throw away the possibility of its progressive enlargement and transmutation into divinity. India suffered badly rejecting life and the purpose of creation. Life though distorted by Maya has a purpose. It prepares man for the higher truths.
Optimism fades with age, and some remain unaware of others' suffering, as seen in those who never experience hardship.
