Spiritual effort (sadhana) requires regular habits and moderation in food, sleep and exercise. The body, the mind and the spirit, all three must be equally looked after.  Unless you have "muscles of iron and nerves of steel" you cannot contain in your head the adhwaitha (Oneness with the Universe) principle. To see Truth as Truth and untruth as untruth, clarity of vision and courage of vision are both needed.  You have come into this world to enter the presence of Lokesha (Lord of the Universe).  So, do not tarry in wayside inns, mistaking them to be the goal.  The Lord will be longing for the arrival of the lost, He is like a cow yearning for its calf.

"The Lord is sweet in every one of His actions, movement, words and gestures.  He is sweetness itself"- Baba
