Eyal Shaham is a programmer, certified yoga teacher, whistleblower and activist. In recent years he has focused on raising awareness of the International School of Temple Arts (ISTA), an organisation critics describe as a harmful cult. His work includes speaking with journalists and authorities and helping survivors seek recognition and support, and he created the website istaAwareness.life as part of his advocacy. ISTA has recently filed a $1 million lawsuit against him in Israel.
