A seeker often gets bad thoughts during meditation I mean " simply bad thoughts" ( I simply leave it to the imagination of the readers about the bad thoughts) and he complains it to his master about his experience.
The master says " just ignore them ". He continued" when devas and asuras churned the ocean the first thing they received was poisonous fumes and elements but, they never bothered about the outcome they just continued churning . Ultimately, they explored the elixir .Likewise, you should not bother about the outcome just continue what you are doing right now the rest is HIS discretion".
