Peace is necessary for all; without peace and an increasing purity, even if one opens, one cannot receive perfectly all that comes down through the opening. Light too is necessary for all—without light one cannot take full advantage of all that comes down. <ref>http://incarnateword.in/cwsa/29/peace-the-basis-of-the-sadhana#p2</ref>
= Yoga and Purity =
Thus purification, liberation, perfection, delight of being are four constituent elements of the Yoga,—śuddhi, mukti, siddhi, bhukti. <ref> http://incarnateword.in/cwsa/24/the-perfection-of-the-mental-being#p12 </ref>
Very often the earlier stage of the sadhana is successful, because there is an opening of the mind to first workings of the Force—afterwards the lower vital consciousness and the physical rise up and if these are not ready or inclined for the sadhana, it ceases. The sadhaka has first to purify and open them and call in the Force to work there and make all ready until he can bring the true consciousness and experience there. Yoga implies a long and difficult work and one must be ready to accept the necessity of years of preparation and purification and increasing consecration before the greater results can come. <ref>http://incarnateword.in/cwsa/29/purity#p7</ref>
With the inner liberation, with a total sincerity and perfect purity, all suffering will disappear, because it will no longer be necessary for the progress of the consciousness towards its final goal. <ref>http://incarnateword.in/cwm/03/the-fool#p21</ref>
