It was first released in the United Kingdom in 1996 as "Tattva (Lucky 13 Mix)", then re-issued on 24 June 1996 as a re-recording from their debut album, K (1996), with a different sleeve and track listing.

In Melody Maker, critic Neil Kulkarni declared "Tattva" and follow-up release "Grateful When You're Dead" to be "the two worst singles of '96".

Not that the word acintya would necessarily correspond to the Western idea of God, but the same kind of ineffable mystery is implied here.

The "Lucky 13 Mix" was issued on 7-inch vinyl and CD in the United Kingdom, with both formats including "Hollow Man (Part II)" as the B-side.

The first CD includes "Moonshine" and the "Lucky 13 Mix" as its exclusive tracks, and the second disc contains "Red Balloon (Vishnu's Eyes)".
