Your wishes, i.e. desires to obtain something, are not acheived by any mantra, tantra* or yantra^. Your physical and mental steps towards the fruit of such desires/wishes will get you your wishes. Take it from the OG Adi Shankara himself -
Viveka ChoodAmaNi
Chittasya shuddhaye karma, na tu vastu-upalabdhaye;
vastu-siddhi vichAreNa, na kinchit karma kOtibhi hi!
Meaning: Karma kAryAs* results only in cleansing of your subconsciousness (mind), but not in your acheiving any pursuit; inquiring into/about the fruit of your desires/wishes will result in your acheiving your wishes; but even a crore/10 million karma kAryAs also will not help you get even an miniscule part of your wishes.
