No spiritual study or Sadhana can help unless he makes the effort himself. And when the heart is purified, it becomes a worthy abode for the Divine. Whatever you do, you must regard it as a duty done without any motive of self-interest or selfish gain. It is only when all actions, whether they be Yagas or Yajnas or Tapas or any kind of Sadhana, are done as offering to the Divine will they become sanctified and liberating. (SS Oct 12, p. 333)
