All worldly pursuits have but the one unavoidable end, which is sorrow: acquisitions end in dispersion; buildings in destruction; meetings in separation; births, in death. Knowing this, one should, from the very first, renounce acquisition and heaping up, and building, and meeting; and faithful to the commands of an eminent guru, set about realizing the Truth (which has no birth or death)
