We have all grown up listening to stories of ancient warriors being blessed with divine weapons given by various deities. Those Astras and Shastras, existed then and exist even today. The difference is in the capacity of beings to manifest them. While till Dwaparyuga, men had the capacity and purity of sadhna to manifest the various Astras into physical form, in kaliyug these Astras can be accessed in the etheric dimension through sadhna of their respective deities, under the guidance of a Guru and also put to use. To quote from recent history, Guru Gobind Singh had the vision of a Divine Sword after the completion of the havan that established Khalsa. Talking of now, sadhaks at Dhyan Ashram describe many such Astras and Shastras, which they accessed during dhyan. While these weapons empower you, one must one forget they are bestowed by shaktis that run the creation and work only when put to use for creation...Any counter practices cause one to lose their entitlements…Hence the role of the Guru who prepares the being and bestows him/her with the experiences as per his/her capacity. Certain practitioners at the ashram have the ability to call them when required.
