How soon can one expect to experience the benefits of wearing or installing a Yantra?. Yantras usually takes 45 days but this is a conservative estimate. Some Yantras activate results almost immediately if one's karmic potential is ripe. Others work better over the long term, gradually but steadfastly increasing stages of blessings. Yantras for prosperity and wealth are usually of this category. Hence patience is required. For example, the Lord Kuber Yantra may or may not bestow immediate results but the patient person will eventually see benefits.
