In Vajrayana Buddhism, it's important to transform absolutely every moment and every experience into a pure one, a Dharmic one. This means even spitting, blowing one's nose, coughing up phlegm, urinating, and defecating. There's nothing that cannot be lam khyer, "brought to the path," if one knows the skillful means to do so. So below is yet another entry from the gZungs 'Dus (Collection of Dharanis) from the Kangyur. It consists of a series of mantra in order to transform one's bodily wastes into an offering to other sentient beings as an expression of one's Bodhicitta or Bodhisatvic motivation. In general, one thinks that, by saying these mantras at the time of urinating, defecating, etc., the mantras turn the waste material into a pure food offering for any animals or microscopic beings that may consume such waste products. Thus these animals and microscopic beings receive the pleasure of sustenance as well as, and even more importantly, a connection to the Dharma. Having made such a connection, it is now assured that, in some future life, they will practice the Dharma and achieve Enlightenment or Awakening. So this is a huge act of charity and, as such, it accumulates a huge store of merit. This skillful means transforms something we all have to do every day in any case into a Bodhisatvic act for the sake of all beings. How marvelous and how easy!
Dharani for Offering the Outflows of the Body as Charity
KON-CHOG SUM-LA CHAG-TSHAL LO
I prostrate to the Three Jewels.
Dharani for offering the outflows of the body as charity.
For spit: OM AH SHLEM-HA RE-BHYA SO-HA

By uttering these, may each of these be transformed into food. May all the merit from this stainless charity be dedicated to the purpose of the Awakening of all sentient beings. These have been taken from [various] Sutras and Tantras of the One from Vajrasana. Translated by Bari Lotsawa.
