Verse 19
भवप्रत्ययो विदेहप्रकृतिलयानम् ॥१९॥
bhava-pratyayo videha-prakrti-layānam ॥19॥
bhava = being, becoming
pratyayah = perception, thought, intention, representation
videha = bodiless
prakriti = nature
layaanaam = clasped, merged
in 1.19 he patanjali says Bhava pratyayo videha prakriti layaanaam
These latent impressions or Samskaras are bodyless in nature and are bound together.
Here he’s indicating that our sadhana and spiritual progress is not gonna go waste after death, its carried by samskaras and they dont die with the body, they are carried on in our next janmas
.This Samadhi, when not followed by extreme non-attachment becomes the cause of the re-manifestation of the gods and of those that become merged in nature
