Answer

“Bela tap” is not usually counted as one of the fixed 20 pads of Vish-Sthanak Tap/Oli. Vish-Sthanak Tapa is described as having 20 different pads, and in each pad one does a minimum of 20 ekasan to attham according to the tradition being followed. In Jain usage, “bela” generally means two upvas (two consecutive fasts), so it is a type of fasting, not a standard pad number. ( jainfoundation.in)

Explanation

If you actually meant Navpad Oli, that is different: Navpad Oli has 9 pads, and the 9th day is Samyag Tap Pad. So “bela tap” does not match the usual Navpad pad names either. ( oshwal.org.uk)

Spiritual Understanding

In Jain Dharma, the main purpose of tap is self-control, inner purity, and karmic shedding. The exact form of tap can vary, but the spiritual goal remains the same: reduce attachment and strengthen discipline. ( jaina.org)

Takeaway

So the simplest answer is: Bela tap is a fasting practice, not a fixed pad in Vish-Sthanak Oli. ( gujarat-samachar.com)
