Shaila freely shares many of her talks on diverse aspects of the dhamma through the IMSB portal of the Dharma Seed Library. Shaila does not, however, share in-depth teachings on jhāna and concentration so publically. She has found that more context is required for the subtle teachings of jhāna to be wisely undertaken and integrated into practice with a right view of the path. Therefore, her teachings on jhāna are only available in formats that provide suitable contexts for the training. You can find jhāna instructions in her books, retreats, and online courses.
