Why Gloom and Difficulties

The gloom and other difficulties come from a resistance of inertia in the lower vital and physical consciousness. What you have to do is to prepare the consciousness by getting rid of the inertia. A sattwic gladness and calm and confidence is the proper temperament for this yoga; gloom, depression and weeping should not be indulged in, as they stand in the way of the opening, unless the tears are the psychic weeping of release or adoration or a moved love and bhakti. The progress made in controlling the sex and other rajasic movements of the lower vital is a good preparation, but not enough; by itself it is only the negative side, though indispensable. Aspire for a positive sattwic opening for strength, for light, for peace and do not worry or repine if the progress is slow at first, nor grudge the time and labour of preparation necessary before there can be a rapid advance in the yoga.
