क्लेशमूलः कर्माशयो दृष्टादृष्टजन्मवेदनीयः

klesa mulah karmasayodrstadrsta janma vedaniyah

Karma seen and unseen in this life has it’s root in the obstacles.

Yoga Sutras of Patanjali, 2.12

klesa = obstacles
mulah = root
karma = karma (cycle of cause and effect)
asayo = reservoir, womb
drsta = seen
adrsta = unseen
janma = birth
vedaniyah = experienced

When seemingly bad events happen, perhaps it’s that we are only able to see a part of it, and if we could see the whole of it, things would be OK.
