Bhagavad Gita: For the doubting soul there is happiness neither in this world nor in the next (Text 40, Ch 4, Transcendental Knowledge)

ajnas casraddadhanas ca

samsayatma vinasyati

nayam loko' sti na paro

na sukham samsayatmanah

(Text 40, Ch 4, Transcendental Knowledge)

Meaning: But ignorant and faithless persons who doubt the revealed scriptures do not attain God consciousness; they fall down. For the doubting soul there is happiness neither in this world nor in the next.

*** Doubtful persons have no status whatsoever in spiritual emancipation.Those who have no faith and are always doubtful make no progress at all. Men without faith in God and his revealed word find no good in this world, nor in the next. For them there is no happiness whatsoever.
