the evidence for epigenetics is actually very flimsy and epigenetics in humans may well not be a thing at all. Even with other species, the effect never lasts for more than a few generations.
There's a very good summary of the epigenetics matter in Adam Rutherford's "A Brief History of Everyone Who Ever Lived", pp 344-351.
Rutherford's dismissal of New-Age hijacking of such ideas is trenchant:
New Age gurus and gullible journalists cite epigenetics as a way of changing your life, under the false supposition that genes are destiny, and epigenetic changes brought on by life-style choices such as meditation "allows us almost unlimited influence on our fate" (Deepak Chopra)
