When bindu mixed with rajas, and rajas united with bindu, they become of the same flavor — that is called the siddhi of Vajrolī.

This verse describes Vajrolī’s successful outcome using the technical term sama-rasī-bhūtam — becoming of the same flavor (rasa).This concept of samarasa is central to Tantrism, meaning the dissolution of all dualities into a unified experience.

Rajasā recitam bindum — bindu poured with rajas — and miśrī-bhūtam rajaḥ — mixed rajas — describe the physical union of the male and female essences.But the real achievement is not the physical mixture but the transformation into sama-rasa.

Sama means equal, same;rasa means flavor, essence, experience.When bindu and rajas merge completely, there are no longer two substances but one non-dual experience.The practitioner experiences the unity of Śiva and Śakti directly, not as a philosophical concept but as a lived reality.

Vajrolī-siddhiḥ — the siddhi of Vajrolī — is precisely this state of samarasa.The powers mentioned above (longevity, immunity, etc.) are side effects;the true achievement is the direct experience of non-duality.
