The Lord is everyone’s friend, but He is especially friendly to the surrendered soul. The simple process, therefore, is that a conditioned soul should remain surrendered to the Lord and the Lord will give him all protection to keep him out of the clutches of material contamination.
When you surrender that's where you get your strength from.
One should surrender fully to the Lord, forgetting one’s so called material happiness, opulence and education, which are not at all useful for pleasing the Lord. The Lord is pleased only by the process of surrender unto Him.
