Struggle to realise Atma, to visualise God, even failure in this struggle is noble than the success in other worldly affairs. (Ddd, p. 11)

You must struggle; you cannot go to the top without struggle. Have faith in ultimate victory. Gather courage and faith from wherever you get them. Do not mix with those who sow the seeds of fear and doubt. Treasure all the confidence and courage you get from here. Do not let them slip from your grasp. Then you get maximum profit from my words. (LS, p. 104)
